The plants that are likely most familiar to us are the multicellular land plants, called embryophytes. Embryophytes include the vascular plants, such as ferns, conifers and flowering plants. They also include the bryophytes, of which mosses and liverworts are the most common.

All of these plants have eukaryotic cells with cell walls composed of cellulose, and most obtain their energy through photosynthesis, using light, water and carbon dioxide to synthesize food. About three hundred plant species do not photosynthesize but are parasites on other species of photosynthetic plants. Embryophytes are distinguished from green algae, which represent a mode of photosynthetic life similar to the kind modern plants are believed to have evolved from, by having specialized reproductive organs protected by non-reproductive tissues.

Bryophytes first appeared during the early Paleozoic. They mainly live in habitats where moisture is available for significant periods, although some species, such as Targionia, are desiccation-tolerant. Most species of bryophytes remain small throughout their life-cycle. This involves an alternation between two generations: a haploid stage, called the gametophyte, and a diploid stage, called the sporophyte. In bryophytes, the sporophyte is always unbranched and remains nutritionally dependent on its parent gametophyte. The embryophytes have the ability to secrete a cuticle on their outer surface, a waxy layer that confers resistant to desiccation. In the mosses and hornworts a cuticle is usually only produced on the sporophyte. Stomata are absent from liverworts, but occur on the sporangia of mosses and hornworts, allowing gas exchange.

Vascular plants first appeared during the Silurian period, and by the Devonian had diversified and spread into many different terrestrial environments. They developed a number of adaptations that allowed them to spread into increasingly more arid places, notably the vascular tissues xylem and phloem, that transport water and food throughout the organism. Root systems capable of obtaining soil water and nutrients also evolved during the Devonian. In modern vascular plants, the sporophyte is typically large, branched, nutritionally independent and long-lived, but there is increasing evidence that Paleozoic gametophytes were just as complex as the sporophytes. The gametophytes of all vascular plant groups evolved to become reduced in size and prominence in the life cycle.

In seed plants, the microgametophyte is reduced from a multicellular free-living organism to a few cells in a pollen grain and the miniaturised megagametophyte remains inside the megasporangium, attached to and dependent on the parent plant. A megasporangium enclosed in a protective layer called an integument is known as an ovule. After fertilisation by means of sperm produced by pollen grains, an embryo sporophyte develops inside the ovule. The integument becomes a seed coat, and the ovule develops into a seed. Seed plants can survive and reproduce in extremely arid conditions, because they are not dependent on free water for the movement of sperm, or the development of free living gametophytes.

The first seed plants, pteridosperms (seed ferns), now extinct, appeared in the Devonian and diversified through the Carboniferous. They were the ancestors of modern gymnosperms, of which four surviving groups are widespread today, particularly the conifers, which are dominant trees in several biomes. The name gymnosperm comes from the Greek composite word γυμνόσπερμος (γυμνός gymnos, “naked” and σπέρμα sperma, “seed”), as the ovules and subsequent seeds are not enclosed in a protective structure (carpels or fruit), but are borne naked, typically on cone scales.

Plant fossils include roots, wood, leaves, seeds, fruit, pollen, spores, phytoliths, and amber (the fossilized resin produced by some plants). Fossil land plants are recorded in terrestrial, lacustrine, fluvial and nearshore marine sediments. Pollen, spores and algae (dinoflagellates and acritarchs) are used for dating sedimentary rock sequences. The remains of fossil plants are not as common as fossil animals, although plant fossils are locally abundant in many regions worldwide.

The earliest fossils clearly assignable to Kingdom Plantae are fossil green algae from the Cambrian. These fossils resemble calcified multicellular members of the Dasycladales. Earlier Precambrian fossils are known that resemble single-cell green algae, but definitive identity with that group of algae is uncertain.

The earliest fossils attributed to green algae date from the Precambrian (ca. 1200 mya).[57][58] The resistant outer walls of prasinophyte cysts (known as phycomata) are well preserved in fossil deposits of the Paleozoic (ca. 250–540 mya). A filamentous fossil (Proterocladus) from middle Neoproterozoic deposits (ca. 750 mya) has been attributed to the Cladophorales, while the oldest reliable records of the Bryopsidales, Dasycladales) and stoneworts are from the Paleozoic.[46][59]

The oldest known fossils of embryophytes date from the Ordovician, though such fossils are fragmentary. By the Silurian, fossils of whole plants are preserved, including the simple vascular plant Cooksonia in mid-Silurian and the much larger and more complex lycophyte Baragwanathia longifolia in late Silurian. From the early Devonian Rhynie chert, detailed fossils of lycophytes and rhyniophytes have been found that show details of the individual cells within the plant organs and the symbiotic association of these plants with fungi of the order Glomales. The Devonian period also saw the evolution of leaves and roots, and the first modern tree, Archaeopteris. This tree with fern-like foliage and a trunk with conifer-like wood was heterosporous producing spores of two different sizes, an early step in the evolution of seeds.[60]

The Coal measures are a major source of Paleozoic plant fossils, with many groups of plants in existence at this time. The spoil heaps of coal mines are the best places to collect; coal itself is the remains of fossilised plants, though structural detail of the plant fossils is rarely visible in coal. In the Fossil Grove at Victoria Park in Glasgow, Scotland, the stumps of Lepidodendron trees are found in their original growth positions.

The fossilized remains of conifer and angiosperm roots, stems and branches may be locally abundant in lake and inshore sedimentary rocks from the Mesozoic and Cenozoic eras. Sequoia and its allies, magnolia, oak, and palms are often found.

Petrified wood is common in some parts of the world, and is most frequently found in arid or desert areas where it is more readily exposed by erosion. Petrified wood is often heavily silicified (the organic material replaced by silicon dioxide), and the impregnated tissue is often preserved in fine detail. Such specimens may be cut and polished using lapidary equipment. Fossil forests of petrified wood have been found in all continents.

Fossils of seed ferns such as Glossopteris are widely distributed throughout several continents of the Southern Hemisphere, a fact that gave support to Alfred Wegener’s early ideas regarding Continental drift theory.

Most of the solid material in a plant is taken from the atmosphere. Through the process of photosynthesis, most plants use the energy in sunlight to convert carbon dioxide from the atmosphere, plus water, into simple sugars. These sugars are then used as building blocks and form the main structural component of the plant. Chlorophyll, a green-colored, magnesium-containing pigment is essential to this process; it is generally present in plant leaves, and often in other plant parts as well. Parasitic plants, on the other hand, use the resources of their host to provide the materials needed for metabolism and growth.

Plants usually rely on soil primarily for support and water (in quantitative terms), but they also obtain compounds of nitrogen, phosphorus, potassium, magnesium and other elemental nutrients from the soil. Epiphytic and lithophytic plants depend on air and nearby debris for nutrients, and carnivorous plants supplement their nutrient requirements, particularly for nitrogen and phosphorus, with insect prey that they capture. For the majority of plants to grow successfully they also require oxygen in the atmosphere and around their roots (soil gas) for respiration. Plants use oxygen and glucose (which may be produced from stored starch) to provide energy.[61] Some plants grow as submerged aquatics, using oxygen dissolved in the surrounding water, and a few specialized vascular plants, such as mangroves and reed (Phragmites australis),[62] can grow with their roots in anoxic conditions.

The genome of a plant controls its growth. For example, selected varieties or genotypes of wheat grow rapidly, maturing within 110 days, whereas others, in the same environmental conditions, grow more slowly and mature within 155 days.[63]

Growth is also determined by environmental factors, such as temperature, available water, available light, carbon dioxide and available nutrients in the soil. Any change in the availability of these external conditions will be reflected in the plant’s growth and the timing of its development.[citation needed]

Biotic factors also affect plant growth. Plants can be so crowded that no single individual produces normal growth, causing etiolation and chlorosis. Optimal plant growth can be hampered by grazing animals, suboptimal soil composition, lack of mycorrhizal fungi, and attacks by insects or plant diseases, including those caused by bacteria, fungi, viruses, and nematodes.[63]

Simple plants like algae may have short life spans as individuals, but their populations are commonly seasonal. Annual plants grow and reproduce within one growing season, biennial plants grow for two growing seasons and usually reproduce in second year, and perennial plants live for many growing seasons and once mature will often reproduce annually. These designations often depend on climate and other environmental factors. Plants that are annual in alpine or temperate regions can be biennial or perennial in warmer climates. Among the vascular plants, perennials include both evergreens that keep their leaves the entire year, and deciduous plants that lose their leaves for some part of it. In temperate and boreal climates, they generally lose their leaves during the winter; many tropical plants lose their leaves during the dry season.[citation needed]

The growth rate of plants is extremely variable. Some mosses grow less than 0.001 millimeters per hour (mm/h), while most trees grow 0.025-0.250 mm/h. Some climbing species, such as kudzu, which do not need to produce thick supportive tissue, may grow up to 12.5 mm/h.[citation needed]

Plants protect themselves from frost and dehydration stress with antifreeze proteins, heat-shock proteins and sugars (sucrose is common). LEA (Late Embryogenesis Abundant) protein expression is induced by stresses and protects other proteins from aggregation as a result of desiccation and freezing.[64]

When water freezes in plants, the consequences for the plant depend very much on whether the freezing occurs within cells (intracellularly) or outside cells in intercellular spaces.[65] Intracellular freezing, which usually kills the cell[66] regardless of the hardiness of the plant and its tissues, seldom occurs in nature because rates of cooling are rarely high enough to support it. Rates of cooling of several degrees Celsius per minute are typically needed to cause intracellular formation of ice.[67] At rates of cooling of a few degrees Celsius per hour, segregation of ice occurs in intercellular spaces.[68] This may or may not be lethal, depending on the hardiness of the tissue. At freezing temperatures, water in the intercellular spaces of plant tissue freezes first, though the water may remain unfrozen until temperatures drop below −7 °C (19 °F).[65] After the initial formation of intercellular ice, the cells shrink as water is lost to the segregated ice, and the cells undergo freeze-drying. This dehydration is now considered the fundamental cause of freezing injury.

Plants are continuously exposed to a range of biotic and abiotic stresses. These stresses often cause DNA damage directly, or indirectly via the generation of reactive oxygen species.[69] Plants are capable of a DNA damage response that is a critical mechanism for maintaining genome stability.[70] The DNA damage response is particularly important during seed germination, since seed quality tends to deteriorate with age in association with DNA damage accumulation.[71] During germination repair processes are activated to deal with this accumulated DNA damage.[72] In particular, single- and double-strand breaks in DNA can be repaired.[73] The DNA checkpoint kinase ATM has a key role in integrating progression through germination with repair responses to the DNA damages accumulated by the aged seed.[74]

Plant cells are typically distinguished by their large water-filled central vacuole, chloroplasts, and rigid cell walls that are made up of cellulose, hemicellulose, and pectin. Cell division is also characterized by the development of a phragmoplast for the construction of a cell plate in the late stages of cytokinesis. Just as in animals, plant cells differentiate and develop into multiple cell types. Totipotent meristematic cells can differentiate into vascular, storage, protective (e.g. epidermal layer), or reproductive tissues, with more primitive plants lacking some tissue types.[75]

Plants are photosynthetic, which means that they manufacture their own food molecules using energy obtained from light. The primary mechanism plants have for capturing light energy is the pigment chlorophyll. All green plants contain two forms of chlorophyll, chlorophyll a and chlorophyll b. The latter of these pigments is not found in red or brown algae.
The simple equation of photosynthesis is as follows:

By means of cells that behave like nerves, plants receive and distribute within their systems information about incident light intensity and quality. Incident light that stimulates a chemical reaction in one leaf, will cause a chain reaction of signals to the entire plant via a type of cell termed a bundle sheath cell. Researchers, from the Warsaw University of Life Sciences in Poland, found that plants have a specific memory for varying light conditions, which prepares their immune systems against seasonal pathogens.[76] Plants use pattern-recognition receptors to recognize conserved microbial signatures. This recognition triggers an immune response. The first plant receptors of conserved microbial signatures were identified in rice (XA21, 1995)[77] and in Arabidopsis thaliana (FLS2, 2000).[78] Plants also carry immune receptors that recognize highly variable pathogen effectors. These include the NBS-LRR class of proteins.

Vascular plants differ from other plants in that nutrients are transported between their different parts through specialized structures, called xylem and phloem. They also have roots for taking up water and minerals. The xylem moves water and minerals from the root to the rest of the plant, and the phloem provides the roots with sugars and other nutrient produced by the leaves.[75]

Plants have some of the largest genomes among all organisms.[79] The largest plant genome (in terms of gene number) is that of wheat (Triticum asestivum), predicted to encode ≈94,000 genes[80] and thus almost 5 times as many as the human genome. The first plant genome sequenced was that of Arabidopsis thaliana which encodes about 25,500 genes.[81] In terms of sheer DNA sequence, the smallest published genome is that of the carnivorous bladderwort (Utricularia gibba) at 82 Mb (although it still encodes 28,500 genes)[82] while the largest, from the Norway Spruce (Picea abies), extends over 19,600 Mb (encoding about 28,300 genes).[83]

The photosynthesis conducted by land plants and algae is the ultimate source of energy and organic material in nearly all ecosystems. Photosynthesis, at first by cyanobacteria and later by photosynthetic eukaryotes, radically changed the composition of the early Earth’s anoxic atmosphere, which as a result is now 21% oxygen. Animals and most other organisms are aerobic, relying on oxygen; those that do not are confined to relatively rare anaerobic environments. Plants are the primary producers in most terrestrial ecosystems and form the basis of the food web in those ecosystems. Many animals rely on plants for shelter as well as oxygen and food.[citation needed]

Land plants are key components of the water cycle and several other biogeochemical cycles. Some plants have coevolved with nitrogen fixing bacteria, making plants an important part of the nitrogen cycle. Plant roots play an essential role in soil development and the prevention of soil erosion.[citation needed]

Plants are distributed almost worldwide. While they inhabit a multitude of biomes and ecoregions, few can be found beyond the tundras at the northernmost regions of continental shelves. At the southern extremes, plants of the Antarctic flora have adapted tenaciously to the prevailing conditions.[citation needed]

Plants are often the dominant physical and structural component of habitats where they occur. Many of the Earth’s biomes are named for the type of vegetation because plants are the dominant organisms in those biomes, such as grasslands, taiga and tropical rainforest.[citation needed]

Numerous animals have coevolved with plants. Many animals pollinate flowers in exchange for food in the form of pollen or nectar. Many animals disperse seeds, often by eating fruit and passing the seeds in their feces. Myrmecophytes are plants that have coevolved with ants. The plant provides a home, and sometimes food, for the ants. In exchange, the ants defend the plant from herbivores and sometimes competing plants. Ant wastes provide organic fertilizer.

The majority of plant species have various kinds of fungi associated with their root systems in a kind of mutualistic symbiosis known as mycorrhiza. The fungi help the plants gain water and mineral nutrients from the soil, while the plant gives the fungi carbohydrates manufactured in photosynthesis. Some plants serve as homes for endophytic fungi that protect the plant from herbivores by producing toxins. The fungal endophyte, Neotyphodium coenophialum, in tall fescue (Festuca arundinacea) does tremendous economic damage to the cattle industry in the U.S.

Various forms of parasitism are also fairly common among plants, from the semi-parasitic mistletoe that merely takes some nutrients from its host, but still has photosynthetic leaves, to the fully parasitic broomrape and toothwort that acquire all their nutrients through connections to the roots of other plants, and so have no chlorophyll. Some plants, known as myco-heterotrophs, parasitize mycorrhizal fungi, and hence act as epiparasites on other plants.

Many plants are epiphytes, meaning they grow on other plants, usually trees, without parasitizing them. Epiphytes may indirectly harm their host plant by intercepting mineral nutrients and light that the host would otherwise receive. The weight of large numbers of epiphytes may break tree limbs. Hemiepiphytes like the strangler fig begin as epiphytes but eventually set their own roots and overpower and kill their host. Many orchids, bromeliads, ferns and mosses often grow as epiphytes. Bromeliad epiphytes accumulate water in leaf axils to form phytotelmata that may contain complex aquatic food webs.[84]

Approximately 630 plants are carnivorous, such as the Venus Flytrap (Dionaea muscipula) and sundew (Drosera species). They trap small animals and digest them to obtain mineral nutrients, especially nitrogen and phosphorus.[85]

The study of plant uses by people is called economic botany or ethnobotany.[86] Human cultivation of plants is part of agriculture, which is the basis of human civilization.[87] Plant agriculture is subdivided into agronomy, horticulture and forestry.[88]

Humans depend on plants for food, either directly or as feed for domestic animals. Agriculture deals with the production of food crops, and has played a key role in the history of world civilizations. Agriculture includes agronomy for arable crops, horticulture for vegetables and fruit, and forestry for timber.[89] About 7,000 species of plant have been used for food, though most of today’s food is derived from only 30 species. The major staples include cereals such as rice and wheat, starchy roots and tubers such as cassava and potato, and legumes such as peas and beans. Vegetable oils such as olive oil provide lipids, while fruit and vegetables contribute vitamins and minerals to the diet.[90]

Medicinal plants are a primary source of organic compounds, both for their medicinal and physiological effects, and for the industrial synthesis of a vast array of organic chemicals.[91] Many hundreds of medicines are derived from plants, both traditional medicines used in herbalism[92][93] and chemical substances purified from plants or first identified in them, sometimes by ethnobotanical search, and then synthesised for use in modern medicine. Modern medicines derived from plants include aspirin, taxol, morphine, quinine, reserpine, colchicine, digitalis and vincristine. Plants used in herbalism include ginkgo, echinacea, feverfew, and Saint John’s wort. The pharmacopoeia of Dioscorides, De Materia Medica, describing some 600 medicinal plants, was written between 50 and 70 AD and remained in use in Europe and the Middle East until around 1600 AD; it was the precursor of all modern pharmacopoeias.[94][95][96]

Plants grown as industrial crops are the source of a wide range of products used in manufacturing, sometimes so intensively as to risk harm to the environment.[97] Nonfood products include essential oils, natural dyes, pigments, waxes, resins, tannins, alkaloids, amber and cork. Products derived from plants include soaps, shampoos, perfumes, cosmetics, paint, varnish, turpentine, rubber, latex, lubricants, linoleum, plastics, inks, and gums. Renewable fuels from plants include firewood, peat and other biofuels.[98][99] The fossil fuels coal, petroleum and natural gas are derived from the remains of aquatic organisms including phytoplankton in geological time.[100]

Structural resources and fibres from plants are used to construct dwellings and to manufacture clothing. Wood is used not only for buildings, boats, and furniture, but also for smaller items such as musical instruments and sports equipment. Wood is pulped to make paper and cardboard.[101] Cloth is often made from cotton, flax, ramie or synthetic fibres such as rayon and acetate derived from plant cellulose. Thread used to sew cloth likewise comes in large part from cotton.[102]

Thousands of plant species are cultivated for aesthetic purposes as well as to provide shade, modify temperatures, reduce wind, abate noise, provide privacy, and prevent soil erosion. Plants are the basis of a multibillion-dollar per year tourism industry, which includes travel to historic gardens, national parks, rainforests, forests with colorful autumn leaves, and festivals such as Japan’s[103] and America’s cherry blossom festivals.[104]

While some gardens are planted with food crops, many are planted for aesthetic, ornamental, or conservation purposes. Arboretums and botanical gardens are public collections of living plants. In private outdoor gardens, lawn grasses, shade trees, ornamental trees, shrubs, vines, herbaceous perennials and bedding plants are used. Gardens may cultivate the plants in a naturalistic state, or may sculpture their growth, as with topiary or espalier. Gardening is the most popular leisure activity in the U.S., and working with plants or horticulture therapy is beneficial for rehabilitating people with disabilities.[citation needed]

Plants may also be grown or kept indoors as houseplants, or in specialized buildings such as greenhouses that are designed for the care and cultivation of living plants. Venus Flytrap, sensitive plant and resurrection plant are examples of plants sold as novelties. There are also art forms specializing in the arrangement of cut or living plant, such as bonsai, ikebana, and the arrangement of cut or dried flowers. Ornamental plants have sometimes changed the course of history, as in tulipomania.[105]

Architectural designs resembling plants appear in the capitals of Ancient Egyptian columns, which were carved to resemble either the Egyptian white lotus or the papyrus.[106] Images of plants are often used in painting and photography, as well as on textiles, money, stamps, flags and coats of arms.[citation needed]

Basic biological research has often been done with plants. In genetics, the breeding of pea plants allowed Gregor Mendel to derive the basic laws governing inheritance,[107] and examination of chromosomes in maize allowed Barbara McClintock to demonstrate their connection to inherited traits.[108] The plant Arabidopsis thaliana is used in laboratories as a model organism to understand how genes control the growth and development of plant structures.[109]NASA predicts that space stations or space colonies will one day rely on plants for life support.[110]

Ancient trees are revered and many are famous. Tree rings themselves are an important method of dating in archeology, and serve as a record of past climates.[citation needed]

Plants figure prominently in mythology, religion and literature. They are used as national and state emblems, including state trees and state flowers. Plants are often used as memorials, gifts and to mark special occasions such as births, deaths, weddings and holidays. The arrangement of flowers may be used to send hidden messages.[citation needed]

Weeds are unwanted plants growing in managed environments such as farms, urban areas, gardens, lawns, and parks. People have spread plants beyond their native ranges and some of these introduced plants become invasive, damaging existing ecosystems by displacing native species, and sometimes becoming serious weeds of cultivation.[citation needed]

Plants may cause harm to animals, including people. Plants that produce windblown pollen invoke allergic reactions in people who suffer from hay fever. A wide variety of plants are poisonous. Toxalbumins are plant poisons fatal to most mammals and act as a serious deterrent to consumption. Several plants cause skin irritations when touched, such as poison ivy. Certain plants contain psychotropic chemicals, which are extracted and ingested or smoked, including nicotine from tobacco, cannabinoids from Cannabis sativa, cocaine from Erythroxylon coca and opium from opium poppy. Smoking causes damage to health or even death, while some drugs may also be harmful or fatal to people.[111][112] Both illegal and legal drugs derived from plants may have negative effects on the economy, affecting worker productivity and law enforcement costs.[113][114]

همشهری آنلاین – شهره فرجی:
لیمو، این میوه همه‌کاره را همیشه در یخچالتان داشته باشید.

لیمو، میوه‌ای ترش و همه‌کاره‌ است که تقریبا برای هرچیزی، از گوشت‌های کباب شده گرفته تا بسیاری از پای‌ها و کیک‌های خوشمزه، از آن استفاده می شود.

 در اینجا به 8 علت عمده برای داشتن این میوه‌ پرخاصیت در یخچالتان می‌پردازیم.

1- برای تزیین غذا به کار می‌رود

لیمو

 از پوست لیمو برحسب نوع دستور غذا، به صورت خرد شده یا نوارهای بلند، می‌توان برای تزیین غذا، استفاده کرد.

برای تهیه پوست لیمو، با استفاده از یک چاقوی تیز یا پوست کن، قسمت رنگی پوست لیمو را به صورت نازک برش دهید.

به هنگام برش مواظب باشید گوشت سفید زیر پوست را به همراه پوست نبرید چرا که مزه تلخی دارد و غذا را بدمزه می‌کند.

اگر تهیه پوست لیمو به این روش برای شما سخت است و یا می‌خواهید به مقدار زیاد پوست لیمو تهیه کنید، بهتر است از یک رنده استفاده کنید.

2- مانع از شکستن پوست تخم‌مرغ به هنگام چوشیدن می‌شود

اگر می‌خواهید تخم‌مرغتان سفت شود فکر بدی نیست از لیمو استفاده کنید.

در این روش قبل از پخت،  روی پوست تخم‌مرغ مقداری آب ‌لیمو بمالید تا پوست آن در برابر شکستن مقاوم شود و اگر موقع جوشیدن چند قطره آب ‌لیمو داخل آب آن بریزید، به هنگام استفاده، پوست آن راحت تر جدا می‌شود.

* آیا می دانید با ریختن چند قطره آب‌ لیمو درون آب در حال جوش برنج، می‌توان از سر رفتن آن جلوگیری کرد؟

3-  کاهوهای خراب و پلاسیده را احیا می کند

هیچ چیز مثل کاهوهای خراب و پلاسیده سالاد را خراب نمی‌کند. خوشبختانه لیمو به کاهوها زندگی دوباره می‌دهد و آن‌ها را با طراوت می‌کند.

اگر می‌خواهید کاهوی پلاسیده شما، با طراوت شود در یک کاسه آب سرد چند قطره آب ‌لیمو بریزید و کاهوها را درون آن بگذارید و یک ساعت در یخچال قرار دهید سپس، انگار که معجزه شده باشد، خواهید دید کاملا تازه و سرحال شده و آماده‌اند تا با آن‌ها یک سالاد ترد و خوشمزه درست کنید. 

اما اگر می‌بینید کاهوها خراب‌تر از آن هستند که بتوان آن‌ها را احیا کرد بهتراست دیگر به آن‌ها فکر نکنید و برای شام به فکر مخلفات دیگری باشید.

4- از تغییر رنگ برخی میوه‌ها پیشگیری می‌کند

از لیمو می‌توان برای پیشگیری موقت از تغییر رنگ برخی میوه‌ها که به تازگی برش داده شده، استفاده کرد.

شما می‌توانید با ریختن چند قطره آب ‌لیمو روی میوه‌هایی مانند آووکادو، سیب، گلابی، هلو و زردآلو تا چندین ساعت رنگ اصلی آن‌ها را حفظ کنید.

5- جذب سدیم را کاهش می‌دهد و غذا را خوش طعم می‌کند

چکاندن چند قطره آب ‌لیمو روی غذا، کمک خوبی برای کاهش جذب سدیم خواهد بود .بسیاری از ما، مقدار ناسالمی از سدیم را مصرف می‌کنیم که می‌تواند منجر به فشارخون بالا و افزایش خطر حملات قلبی گردد.

 به طور متوسط، مصرف روزانه آمریکاییها، 7000 میلی‌گرم سدیم در روز است،  در حالیکه بدن، حداکثر به 2300 میلی‌گرم سدیم در روز، نیاز دارد.

لیمو می‌تواند جانشین بدون سدیم خوبی برای کسانی باشد که به دنبال یک چاشنی قوی برای غذای مورد نظرشان هستند.

سعی کنید همیشه روی مرغ، گوشت، غذاهای دریایی و سبزیجاتی که مصرف می‌کنید، چند قطره آب ‌لیمو بریزید.

بسیاری از افراد عقیده دارند، آب ‌لیمو می‌تواند نقش نمک را در غذا ایفا کند. اگر از طعم لیمو خسته شده‌اید، از طعم ترش و خوشمزه نارنج استفاده کنید.

6- ضد سرطان است

لیمو

طبق تحقیقات، نوشیدن چای سبز و سیاه همراه با پوست لیمو در آن، خطر ابتلا به سرطان پوست را تا 75 درصد کاهش می دهد.

از لیمو برای پیشگیری از آفتاب سوختگی نیز استفاده می‌شود. ترکیبات طبیعی موجود در چای همراه با پوست لیمو، بدن را در برابر اشعه UV مضر خورشید که مهمترین عامل ابتلا به سرطان پوست است، محافظت می‌کند.

سعی کنید به جای قهوه‌ای که صبح‌ها می‌خورید،  پوست لیمو را در چای بریزید و بخورید، چرا که قهوه خاصیتی جز بیدار نگه داشتن شما ندارد.

7- رفع خستگی می‌کند

گرمای شدید تابستان، می‌تواند شما را کاملا خسته و فرسوده کند پس، برای اینکه بتوانید شاداب و با طراوت شوید، چند قطره آب ‌لیمو به قالب آبی که داخل جایخی می گذارید اضافه کنید و نگران نباشید که بعد به چه مصرفی خواهد رسید چرا که آب ‌لیموی داخل یخ، تقریبا هر نوشیدنی را خوش طعم‌تر می‌کند.

اگر مزه ترش را می‌توانید تحمل کنید، در قالبی که درون جایخی می‌گذارید، فقط آب ‌لیمو،‌ بریزید و بگذارید یخ ببندد که نتیجه آن، آب‌ لیموی یخ‌زده بسیار ترشی خواهد بود که می‌توان از آن برای هر نوشیدنی که با یخ مصرف می‌شود، استفاده کرد.

8- ضامن سلامتی شماست

Lemons are high in vitamin C, fiber, and various beneficial plant compounds.

These nutrients are responsible for several health benefits.

In fact, lemons may support heart health, weight control, and digestive health.

Here are 6 evidence-based health benefits of lemons.

Lemons are a good source of vitamin C.

لیمو

One lemon provides about 31 mg of vitamin C, which is 51% of the reference daily intake (RDI).

Research shows that eating fruits and vegetables rich in vitamin C reduces your risk of heart disease and stroke (1, 2, 3).

However, it’s not only the vitamin C that is thought to be good for your heart. The fiber and plant compounds in lemons could also significantly lower some risk factors for heart disease (4, 5).

For instance, one study revealed that eating 24 grams of citrus fiber extract daily for a month reduced total blood cholesterol levels (6).

Plant compounds found in lemons — namely hesperidin and diosmin — have also been found to lower cholesterol (7, 8, 9).

Lemons are often promoted as a weight loss food, and there are a few theories as to why this is.

One common theory is that the soluble pectin fiber in them expands in your stomach, helping you feel full for longer.

That said, not many people eat lemons whole. And because lemon juice contains no pectin, lemon juice drinks will not promote fullness in the same way.

Another theory suggests that drinking hot water with lemon will help you lose weight.

However, drinking water is known to temporarily increase the number of calories you burn, so it may be the water itself that is helping with weight loss — not the lemon (10, 11).

Other theories suggest that the plant compounds in lemons may aid weight loss.

Research shows that plant compounds in lemon extracts may help prevent or reduce weight gain in a number of ways (12, 13).

In one study, mice on a fattening diet were given lemon polyphenols extracted from the peel. They gained less weight and body fat than other mice (14).

However, no studies confirm the weight loss effects of lemon compounds in humans.

Kidney stones are small lumps that form when waste products crystallize and build up in your kidneys.

They are quite common, and people who get them often get them repeatedly.

Citric acid may help prevent kidney stones by increasing urine volume and increasing urine pH, creating a less favorable environment for kidney stone formation (15, 16).

Just a 1/2-cup (4 ounces or 125 ml) of lemon juice per day may provide enough citric acid to help prevent stone formation in people who have already had them (17, 18).

Some studies also found that lemonade effectively prevented kidney stones, but the results have been mixed. Other studies have shown no effect (19, 20, 21, 22).

Therefore, more well-conducted studies need to examine whether lemon juice affects kidney stone formation (23, 24, 25).

Iron deficiency anemia is quite common. It occurs when you don’t get enough iron from the foods you eat.

Lemons contain some iron, but they primarily prevent anemia by improving your absorption of iron from plant foods (26, 27).

Your gut absorbs iron from meat, chicken, and fish (known as heme iron) very easily, while iron from plant sources (non-heme iron) not as easily. However, this absorption can be improved by consuming vitamin C and citric acid.

Because lemons contain both vitamin C and citric acid, they may protect against anemia by ensuring that you absorb as much iron as possible from your diet.

A healthy diet rich in fruits and vegetables may help prevent some cancers (28).

لیمو

Some observational studies have found that people who eat the most citrus fruit have a lower risk of cancer, while other studies have found no effects (29, 30, 31).

In test-tube studies, many compounds from lemons have killed cancer cells. However, they may not have the same effect on the human body (32, 33, 34).

Some researchers think that plant compounds found in lemons — such as limonene and naringenin — could have anticancer effects, but this hypothesis needs further investigation (5, 35, 36, 37).

Animal studies indicate that D-limonene, a compound found in lemon oil, does have anticancer properties (38, 39).

Another study used pulp from mandarins that contained the plant compounds beta-cryptoxanthin and hesperidin, which are also found in lemons.

The study discovered that these compounds prevented malignant tumors from developing in the tongues, lungs, and colons of rodents (40).

However, it should be noted that the research team used a very high dose of the chemicals — far more than you would get by eating lemons or oranges.

While some plant compounds from lemons and other citrus fruits may have anticancer potential, no quality evidence suggests that lemons can fight cancer in humans.

Lemons are made up of about 10% carbs, mostly in the form of soluble fiber and simple sugars.

The main fiber in lemons is pectin, a form of soluble fiber linked to multiple health benefits.

Soluble fiber can improve gut health and slow the digestion of sugars and starches. These effects may result in reduced blood sugar levels (41, 42, 43, 44).

However, to get the benefits of fiber from lemons, you need to eat the pulp.

People who drink lemon juice, without the fiber found in the pulp, will miss out on the benefits of the fiber.

Lemons contain a high amount of vitamin C, soluble fiber, and plant compounds that give them a number of health benefits.

Lemons may aid weight loss and reduce your risk of heart disease, anemia, kidney stones, digestive issues, and cancer.

Not only are lemons a very healthy fruit, but they also have a distinct, pleasant taste and smell that make them a great addition to foods and drinks.

The lemon is a popular citrus fruit that is high in vitamin C and many powerful nutrients. Lemons may have numerous benefits for health.

Lemons (Citrus limon) are among the world’s most popular citrus fruits.

They grow on lemon trees and are a hybrid of the original citron and lime.

There are many ways to enjoy lemons, but they taste very sour and are usually not eaten alone or as a whole fruit.

Instead, they’re often a garnish with meals, and their juice is often used to provide a sour flavor. They are a key ingredient in lemonade.

A great source of vitamin C and fiber, lemons contain many plant compounds, minerals, and essential oils.

لیمو

These yellow fruits also have many potential health benefits. Eating lemons may lower your risk of heart disease, cancer, and kidney stones.

This article tells you everything you need to know about lemons.

Lemons contain very little fat and protein. They consist mainly of carbs (10%) and water (88–89%).

A medium lemon provides only about 20 calories.

The nutrients in 1/2 cup (100 grams) of raw, peeled lemon are (1):

The carbohydrates in lemons are primarily composed of fibers and simple sugars, such as glucose, fructose, and sucrose (2).

The main fiber in lemons is pectin.

Soluble fibers like pectin can lower blood sugar levels by slowing down the digestion of sugar and starch (3).

Dietary fibers are an important part of a healthy diet and linked to numerous health benefits (3, 4).

Lemons provide several vitamins and minerals.

Plant compounds are natural bioactive substances found in plants, some of which have powerful health benefits.

The plant compounds in lemons and other citrus fruit may have beneficial effects on cancer, cardiovascular disease, and inflammation (8, 9, 10).

These are the main plant compounds in lemons:

Many of the plant compounds in lemons are not found in high amounts in lemon juice, so it is recommended to eat the whole fruit — excluding the peel — for maximum benefit (16, 17).

Citrus fruits, including lemons, are associated with numerous health benefits.

Their vitamins and fiber, as well as their powerful plant compounds, are likely responsible (18).

Heart disease, including heart attacks and strokes, is the world’s most common cause of death.

Intake of fruits high in vitamin C is linked to reduced heart disease risk (19, 20).

Low levels of vitamin C in the blood are also associated with increased risk of stroke, especially among those who are overweight or have high blood pressure (21, 22).

Intake of isolated fibers from citrus fruits has been shown to decrease blood cholesterol levels, and the essential oils in lemons can protect LDL (bad) cholesterol particles from becoming oxidized (23, 24).

Recent studies in rats show that the plant compounds hesperidin and diosmin may have beneficial effects on some key risk factors for heart disease (25, 26, 27).

The citric acid in lemons may reduce your risk of kidney stones (28, 29).

Some studies have shown that lemon juice and lemonade can be effective at preventing kidney stones, but other studies have found no effect (30, 31, 32).

Anemia is often caused by iron deficiency and most common in pre-menopausal women.

Lemons contain small amounts of iron, but they are a great source of vitamin C and citric acid, which can increase the absorption of iron from other foods (33, 34).

لیمو

Because lemons can enhance the absorption of iron from foods, they may help prevent anemia.

Lemons may help reduce the risk of many types of cancers, including breast cancer. This is thought to be due to plant compounds like hesperidin and d-limonene (35, 36, 37, 38, 39, 40, 41, 42).

Many people drink lemon water — either hot or cold — a few times per day.

The recipe is usually freshly squeezed juice from 1/2–1 lemon in a cup (240 ml) of water.

Drinking water with freshly squeezed lemon may have some health benefits.

Lemon water is a rich source of vitamin C and plant compounds, which can enhance immune function, protect against various diseases, and increase your absorption of iron (5, 20, 34, 35).

The citric acid in lemons decreases your risk of kidney stones by diluting urine and increasing its citrate content (28).

Given that some pulp goes into the mix, pectins in the pulp can promote fullness and feed the friendly bacteria in your gut, therein promoting good health and decreased risk of disease (3).

To top things off, the lemon aroma derived from the essential oils might decrease stress and improve mood (43).

Lemonade should have similar health benefits — except for the frequently added sugar, which is unhealthy when consumed in excess.

طرز تهیه جوجه کباب ماهیتابه ایی

Lemons are generally well tolerated, but citrus fruit may cause allergic reactions in a small number of people (44).

They may also cause contact allergy and skin irritation in people with dermatitis (45).

Lemons are quite acidic, so eating them frequently may be harmful to dental health if your tooth enamel becomes damaged (46).

Lemons are a refreshing fruit usually not eaten whole but rather as a garnish or flavoring.

They are an excellent source of vitamin C, soluble fibers, and plant compounds — all of which can provide health benefits.

Oval in shape with a pronouced bulge on one end, lemons are one of the most versatile fruits around, and contain a high level of vitamin C.

Although the juicy yellow flesh is a little too sour to eat on its own, its citrus fragrance and tartness means it’s wonderful combined with all manner of ingredients and dishes, from sweet to savoury. The bright yellow skin, when zested, can be used as well, making it a kitchen essential.

Find out about the health benefits of lemon water with our guide.

All year round, but at their best from January until March.

Look for unblemished, firm lemons that feel heavy for their size and have no tinges of green (which indicates that they’re underripe). Avoid very pale lemons, as they are older and will contain less juice.

The best lemons for juicing or using for wedges are those with a smooth, thin skin. The best for zesting are those with a thicker, knobbly skin, which tend to be on the large size.

If you intend to use the zest, buy unwaxed lemons (shops should state this clearly). If you can’t find them, scrub the lemons thoroughly before zesting.

To extract the maximum amount of juice, make sure the lemons are at room temperature, then firmly roll them back and forth on a work surface under your palm a couple of times – that helps to break down some of the flesh’s fibres.

Alternatively, microwave lemons for around 30 seconds, depending on the size of the lemon – warming them up helps them give up more juice.

In the fridge (for a couple of weeks) or in a fruit bowl (for around one week). Once cut, wrap and keep in the fridge for up to four days.

Serve fresh wedges or slices with fish or add to the pan when roasting veg or meat. Add the zest to salads, baking or sauces. Use the juice to make salad dressings, lemonade, deglaze a pan or add a couple of drops to water to make acidulated water. Use the flesh and peel in marmalades and preserves. Halve and use to stuff a chicken before roasting.

Try lime.

Lemons are a popular fruit that people use in small quantities to add flavor to food. However, they rarely consume them alone due to their intense, sour taste.

Lemons give flavor to baked goods, sauces, salad dressings, marinades, drinks, and desserts, and they are also a good source of vitamin C.

One 58 gram (g) lemon can provide over 30 milligrams (mg) of vitamin C.

Vitamin C is essential for health, and a deficiency can lead to health problems. The early explorers knew this and took lemons on their long voyages to help prevent or treat scurvy, a life threatening condition that was common among sailors.

This article looks at the nutritional content of lemons, their possible health benefits, ways to use them in food, and any potential health risks.

Lemons are an excellent source of vitamin C and flavonoids, which are antioxidants.

Antioxidants help remove free radicals that can damage cells from the body.

These nutrients can help prevent diseases and boost health and wellbeing.

Here some of the possible benefits of consuming lemons.

According to a 2012 study, the flavonoids in citrus fruits may help lower the risk of ischemic stroke in women.

A study of data from nearly 70,000 women over 14 years showed that those who ate the most citrus fruits had a 19% lower risk of ischemic stroke than women who consumed the least.

Ischemic stroke is the most common type of stroke. It can happen when a blood clot blocks the flow of blood to the brain.

A 2019 population study showed that long term, regular consumption of foods that contain flavonoids might help protect against cancer and cardiovascular disease. However, the study indicated that people who smoked or consumed a lot of alcohol were less likely to benefit.

Potassium may help lower the risk of stroke. Which foods contain potassium?

One 2014 study found that women in Japan who walked regularly and consumed lemon every day had lower blood pressure than those who did not.

More research is needed to identify the role of lemon in this improvement and to discover whether consuming lemon can help reduce blood pressure since walking daily can also lower blood pressure.

Which other foods can help lower blood pressure? Find out here.

Lemons and lemon juice are an excellent source of the antioxidant vitamin C.

Antioxidants may help prevent free radicals from causing cell damage that can lead to cancer. However, exactly how antioxidants can help prevent cancer remains unclear.

Which other foods are high in antioxidants? Find out here.

Vitamin C plays a vital role in the formation of collagen, the support system of the skin.

Sun exposure, pollution, age, and other factors can result in skin damage. A 2014 mouse study suggested that either eating vitamin C in its natural form or applying it topically can help prevent this type of damage.

What are the best foods for vitamin C? Find out here.

People with asthma who consume higher amounts of vitamin C and other nutrients when they have a cold may experience fewer asthma attacks, according to one review.

The authors found evidence that vitamin C also benefitted people with bronchial hypersensitivity when they also had a common cold.

However, they called for more research.

Iron deficiency is a leading cause of anemia.

Pairing foods that are high in vitamin C with iron-rich foods maximizes the body’s ability to absorb iron.

However, a high intake of vitamin C can trigger gastrointestinal problems in people who are taking iron supplements. For this reason, it is best to obtain iron from dietary sources, such as beef liver, lentils, raisins, dried beans, animal meats, and spinach.

Squeezing a little lemon juice onto a salad containing baby spinach leaves can help maximize the intake of both iron and vitamin C.

Foods that are high in vitamin C and other antioxidants may help strengthen the immune system against the germs that cause the common cold and the flu.

One review found that, while vitamin C supplements do not appear the reduce the incidence of colds in a population, they may help reduce the length of time a cold lasts. Vitamin C may also help boost immunity in people who are undergoing extreme physical activity.

Squeezing a whole lemon into a glass of hot water with a large spoonful of honey makes a soothing drink for someone with a cough or cold.

In a 2008 study, rodents who consumed lemon peel phenols with a high fat diet for 12 weeks gained less weight than those who did not consume lemon.

In 2016, 84 premenopausal Korean women with a high body mass index (BMI) followed a lemon detox diet or another diet for 7 days. Those who followed the lemon detox diet experienced greater improvements in insulin resistance, body fat, BMI, body weight, and waist-hip ratio than those on the other diets.

Further research is needed to confirm whether lemon can contribute to weight loss, and if so, how.

Vitamin C is an essential nutrient and an antioxidant.

If a person does not consume enough vitamin C, they will develop a deficiency, which is known as scurvy. It is rare in the United States, but it can affect people who do not have a varied diet.

Symptoms can start to appear within a month of not consuming vitamin C, and they include:

Many of these happen when the connective tissues weaken due to the lack of vitamin C.

Since vitamin C helps the body absorb iron, people who are deficient in iron may also develop anemia.

Why do we need vitamin C? Find out here.

One lemon weighing 58 grams (g) contains:

Current dietary guidelines recommend an intake of 75 mg of vitamin C per day for women aged 19 years and older and 90 mg per day for men.

Smokers need 35 mg per day more than nonsmokers.

Lemons also contain small amounts of thiamin, riboflavin, vitamin B-6, pantothenic acid, copper, and manganese.

لیمو

Unlike many fruits, lemons do not ripen or improve in quality after picking. People should harvest lemons when they are ripe and store them at room temperature away from direct sunlight.

Lemons pair well with both savory and sweet dishes.

The following healthful recipes use lemons:

Squeeze fresh lemon juice onto fish, shrimp, scallops, chicken.

Dress salads with fresh lemon juice and a small amount of olive oil with herbs instead of using a commercial product. Premade dressings often contain additional salt, sugar, and other additives, and they can be high in fat and calories.

Lemon squeezers and juicers are available for purchase online.

Some people say that lemon water has a wide range of benefits, from weight loss to relieving depression.

In high enough quantities, the various nutrients in lemon may produce these health benefits.

However, consuming lemon water instead of juice or soda might be beneficial because it reduces a person’s intake of sugar.

Drinking plenty of lemon water can also help prevent dehydration.

Lemons have a high acid content, so their juice may affect people with:

Learn more here about detox drinks and what they can and cannot do.

The nutrients in lemons offer several health benefits. However, it is difficult to obtain all the necessary nutrients from lemon due to its sour taste and high acid content.

However, consuming lemon juice as part of a varied diet that includes plenty of other fresh fruits and vegetables can make a person’s diet more nutritious and healthful.

Is bottled lemon juice as nutritious as fresh lemons?

The 100% bottled lemon juice is suitable for some food preparation applications, such as canning, where the acidity of the product must be high enough to produce the desired reaction.

However, bottled lemon juice does not have the same vitamin C content as fresh lemon juice. It is important to note that vitamin C is sensitive to light and heat and will diminish rather quickly in fresh lemon juice if people do not store it in a cool, dark environment in a non-metal container.
