''Hydroponics - Indoor Horticulture'' [http://www.hydroponicist.com]</ref>]] '''Botany''', '''plant science(s)''', '''phytology''', or '''plant biology''' is a branch of [[biology]] and is the [[Scientific method|scientific study]] of plant [[life]] and development. Botany covers a wide range of scientific disciplines that study [[plant]]s, [[algae]], and [[fungi]] including: [[Plant anatomy|structure]], [[cell growth|growth]], [[reproduction]], [[metabolism]], [[morphogenesis|development]], [[phytopathology|diseases]], and chemical properties and evolutionary relationships between the different groups. The study of plants and botany began with tribal lore, used to identify edible, medicinal and poisonous plants, making botany one of the oldest sciences. From this ancient interest in plants, the scope of botany has increased to include the study of over 550,000 kinds or species of living organisms. ==Scope and importance of botany== [[Image:Beli-hibiskus.jpg|left|thumb|250px|[[Hibiscus]]]]As with other life forms in biology, plant life can be studied from different perspectives, from the [[molecular biology|molecular]], [[genetics|genetic]] and [[biochemistry|biochemical]] level through [[organelle]]s, [[cell biology|cells]], [[biological tissue|tissues]], [[organ (anatomy)|organs]], individuals, plant [[population]]s, and communities of plants. At each of these levels a botanist might be concerned with the classification ([[taxonomy]]), structure ([[Plant anatomy|anatomy]] and [[Plant morphology|morphology]]), or function ([[Plant physiology|physiology]]) of plant life. Historically, botany covered all organisms that were not considered to be [[animal]]s. Some of these organisms are no longer considered to be part of the plant [[Kingdom (biology)|kingdom]] &ndash; these include [[fungi]] (studied in [[mycology]]), [[lichen]]s ([[lichenology]]), [[bacterium|bacteria]] ([[bacteriology]]), [[viruses]] ([[virology]]) and single-celled [[alga]]e, which are now grouped as part of the [[Protista]]. However, attention is still given to these groups by botanists, and fungi, lichens, bacteria and [[Photosynthesis|photosynthetic]] protists are usually covered in introductory botany courses. The study of plants has importance for a number of reasons. Plants are a fundamental part of [[life on Earth]]. They generate the [[oxygen]], [[food]], [[fibre]]s, fuel and [[medicine]] that allow higher life forms to exist. Plants also absorb [[carbon dioxide]] through [[photosynthesis]], a minor [[greenhouse gas]] that in large amounts can affect global climate. It is believed that the evolution of plants has changed the global atmosphere of the earth early in the earth's history and [[paleobotany|paleobotanists]] study ancient plants in the fossil record. A good understanding of plants is crucial to the future of human societies as it allows us to: * Produce food to feed an expanding population * Understand fundamental life processes * Produce medicine and materials to treat diseases and other ailments * Understand environmental changes more clearly ===Human nutrition=== [[Image:US long grain rice.jpg|right|thumb|Nearly all the food we eat comes (directly and indirectly) from plants like this American long grain [[rice]].]] Virtually all foods eaten come from plants, either directly from [[staple food]]s and other [[fruit]] and [[vegetables]], or indirectly through [[livestock]] or other animals, which rely on plants for their nutrition. Plants are the fundamental base of nearly all [[food chain]]s because they use the energy from the sun and nutrients from the soil and atmosphere and convert them into a form that can be consumed and utilized by animals; this is what ecologists call the first [[trophic level]]. Botanists also study how plants produce food we can eat and how to increase yields and therefore their work is important in mankind's ability to ''feed the world'' and provide [[food security]] for future generations, for example through [[plant breeding]]. Botanists also study [[weed]]s, plants which are considered to be a nuisance in a particular location. Weeds are a considerable problem in [[agriculture]], and botany provides some of the basic science used to understand how to minimize 'weed' impact in agriculture and native ecosystems. [[Ethnobotany]] is the study of the relationships between plants and people. [[Image:mendel.png|frame|left|[[Gregor Mendel]] laid the foundations of modern genetics from his studies of plants.]] ===Fundamental life processes=== Plants are convenient organisms in which fundamental life processes (like [[cell division]] and [[protein synthesis]] for example) can be studied, without the ethical dilemmas of studying animals or humans. The [[Mendelian inheritance|genetic laws of inheritance]] were discovered in this way by [[Gregor Mendel]], who was studying the way [[peas|pea]] shape is inherited. What Mendel learned from studying plants has had far reaching benefits outside of botany. Additionally, [[Barbara McClintock]] discovered '[[transposon|jumping genes']] by studying [[maize]]. These are a few examples that demonstrate how botanical research has an ongoing relevance to the understanding of fundamental biological processes. ===Medicine and materials=== Many [[medication|medicinal]] and [[recreational drugs]], like [[tetrahydrocannabinol]], [[caffeine]], and [[nicotine]] come directly from the plant kingdom. Others are simple [[Derivative (chemistry)|derivatives]] of botanical natural products; for example [[aspirin]] is based on the pain killer [[salicylic acid]] which originally came from the [[bark]] of [[willow]] trees.<ref name=JMannSecondaryMetabolism>{{cite book | last = Mann | first = J. | title = Secondary Metabolism, 2nd ed. | publisher = Oxford University Press | date = 1987 | location = Oxford | pages = 186-187 | isbn = 0-19-855529-6}}</ref> There may be many [[drug discovery|novel cures for diseases]] provided by plants, waiting to be discovered. Popular [[stimulant]]s like [[coffee]], [[chocolate]], [[tobacco]], and [[tea]] also come from plants. Most [[alcoholic beverage]]s come from [[fermentation (food)|fermenting]] plants such as [[barley]] ([[beer]]), [[rice]] ([[saki]]) and [[grapes]] ([[wine]]). Plants also provide us with many natural materials, such as [[cotton]], [[wood]], [[paper]], [[linen]], [[vegetable oil]]s, some types of [[rope]], and [[rubber]]. The production of [[silk]] would not be possible without the cultivation of the [[mulberry]] plant. [[Sugarcane]], [[rapeseed]], [[soy]] and other plants with a highly-fermentable sugar or oil content have recently been put to use as sources of [[biofuel]]s, which are important alternatives to [[fossil fuel]]s, see [[biodiesel]]. ===Environmental changes=== Plants can also help us understand changes in on our environment in many ways. *Understanding [[habitat destruction]] and [[endangered species|species extinction]] is dependent on an accurate and complete catalog of plant [[systematics]] and taxonomy. *Plant responses to [[ultraviolet|ultraviolet radiation]] can help us monitor problems like the [[ozone depletion]]. *[[palynology|Analyzing pollen]] deposited by plants [[geologic timescale|thousands or millions of years ago]] can help scientists to reconstruct past climates and predict future ones, an essential part of [[climate change]] research. *Recording and analyzing the timing of plant [[biological life cycle|life cycles]] are important parts of [[phenology]] used in climate-change research. *[[Lichens]], which are sensitive to atmospheric conditions, have been extensively used as [[pollution]] indicators. In many different ways, plants can act a little like the '[[canary|miners canary']], an ''early warning system'' alerting us to important changes in our environment. In addition to these practical and scientific reasons, plants are extremely valuable as recreation for millions of people who enjoy [[gardening]], [[horticulture|horticultural]] and [[herb|culinary]] uses of plants every day. ==Etymology== From [[Greek language|Greek]] βοτάνη = "[[pasture]], [[grass]], [[fodder]]", perhaps via the idea of a [[livestock]] keeper needing to know which plants are safe for livestock to eat. ==History== [[Image:Botany.jpg|thumb|right|The traditional tools of a botanist.]] ===Early botany=== ;Ancient India Early examples of plant taxonomy occur in the [[Rigveda]], that divides plants into ''Vrska'' (tree), ''Osadhi'' (herbs useful to humans) and ''Virudha'' (creepers). which are further subdivided. The [[Atharvaveda]] divides plants into eight classes, ''Visakha'' (spreading branches), ''Manjari'' (leaves with long clusters), ''Sthambini'' (bushy plants), ''Prastanavati'' (which expands); ''Ekasrnga'' (those with monopodial growth), ''Pratanavati'' (creeping plants), ''Amsumati'' (with many stalks), and ''Kandini'' (plants with knotty joints). The [[Taittiriya Samhita]] and classifies the plant kingdom into ''vrksa'', ''vana'' and ''druma'' (trees), ''visakha'' (shrubs with spreading branches), ''sasa'' (herbs), ''amsumali'' (a spreading or deliquescent plant), ''vratati'' (climber), ''stambini'' (bushy plant), ''pratanavati'' (creeper), and ''alasala'' (those spreading on the ground). [[Manusmriti]] proposed a classification of plants in eight major categories. [[Charaka Samhitā]] and [[Sushruta Samhita]] and the [[Vaisesika]]s also present an elaborate taxonomy. [[Parashara]], the author of ''Vrksayurveda'' (the science of life of trees), classifies plants into Dvimatrka ([[Dicotyledon]]s) and Ekamatrka ([[Monocotyledon]]s). These are further classified into ''Samiganiya'' ([[Fabaceae]]), ''Puplikagalniya'' ([[Rutaceae]]), ''Svastikaganiya'' ([[Cruciferae]]), ''Tripuspaganiya'' ([[Cucurbitaceae]]), ''Mallikaganiya'' ([[Apocynaceae]]), and ''Kurcapuspaganiya'' ([[Asteraceae]]).<ref>http://www.infinityfoundation.com/mandala/t_es/t_es_tiwar_botany_frameset.htm</ref> Important medieval Indian works of plant physiology include the ''Prthviniraparyam'' of [[Udayana]], ''Nyayavindutika'' of Dharmottara, ''Saddarsana-samuccaya'' of Gunaratna, and ''Upaskara'' of Sankaramisra.<ref>http://www.infinityfoundation.com/mandala/t_es/t_es_tiwar_botany_frameset.htm</ref> ;Ancient China In [[ancient China]], the recorded listing of different plants and herb concoctions for [[pharmaceutical]] purposes spans back to at least the [[Warring States]] (481 BC-221 BC). Many Chinese writers over the centuries contributed to the written knowledge of herbal pharmaceutics. There was the [[Han Dynasty]] (202 BC-220 AD) written work of the [[Huangdi Neijing]] and the famous pharmacologist [[Zhang Zhongjing]] of the 2nd century. There was also the 11th century scientists and statesmen [[Su Song]] and [[Shen Kuo]], who compiled treatises on herbal medicine and included the use of [[mineralogy]]. ;Greco-Roman world Among the earliest of botanical works in Europe, written around [[300 B.C.]], are two large treatises by [[Theophrastus]]: ''On the History of Plants'' (''[[Historia Plantarum]]'') and ''On the Causes of Plants''. Together these books constitute the most important contribution to botanical science during antiquity and on into the Middle Ages. The Roman medical writer [[Dioscorides]] provides important evidence on Greek and Roman knowledge of medicinal plants. ===Medieval botany=== {{main|Muslim Agricultural Revolution}} The [[Kurdish people|Kurdish]] biologist [[Al-Dinawari]] (828-896) is considered the founder of [[Muslim Agricultural Revolution#Agricultural sciences|Arabic botany]] for his ''Book of Plants'', in which he described at least 637 plants and discussed [[plant evolution]] from its birth to its death, describing the phases of [[plant growth]] and the production of flowers and fruit.<ref name=Fahd-815>{{citation|last=Fahd|first=Toufic|contribution=Botany and agriculture|pages=815}}, in {{Harvard reference |last1=Morelon |first1=Régis |last2=Rashed |first2=Roshdi |year=1996 |title=[[Encyclopedia of the History of Arabic Science]] |volume=3 |publisher=[[Routledge]] |isbn=0415124107}}</ref> In the early 13th century, the [[Al-Andalus|Andalusian]]-[[Arab]]ian biologist Abu al-Abbas al-Nabati developed an early [[scientific method]] for botany, introducing [[empirical]] and [[experiment]]al techniques in the testing, description and identification of numerous [[materia medica]], and separating unverified reports from those supported by actual tests and [[observation]]s.<ref>{{Citation |first=Toby |last=Huff |year=2003 |title=The Rise of Early Modern Science: Islam, China, and the West |page=218 |publisher=[[Cambridge University Press]] |isbn=0521529948 |pages=813-852}}</ref> His student [[Ibn al-Baitar]] (d. 1248) wrote a [[Pharmacy|pharmaceutical]] encyclopedia describing 1,400 [[plant]]s, [[food]]s, and [[drug]]s, 300 of which were his own original discoveries. A [[Latin]] translation of his work was useful to European biologists and pharmacists in the 18th and 19th centuries.<ref>Diane Boulanger (2002), "The Islamic Contribution to Science, Mathematics and Technology", ''OISE Papers'', in ''STSE Education'', Vol. 3.</ref> ===Early modern botany=== In 1665, using an early microscope, [[Robert Hooke]] discovered [[cell (biology)|cells]] in [[cork (material)|cork]], and a short time later in living plant tissue. The [[Germans|German]] [[Leonhart Fuchs]], the Swiss [[Conrad von Gesner]], and the British authors [[Nicholas Culpeper]] and [[John Gerard]] published herbals that gave information on the medicinal uses of plants. In 1754 [[Carolus Linnaeus|Carl von Linné]] (Carl Linnaeus) divided the plant Kingdom into 25 classes. One, the ''Cryptogamia'', included all the plants with concealed reproductive parts (algae, fungi, mosses and liverworts and ferns).<ref name="Hoek, Mann and Jahns 95">'''Hoek, C.van den, Mann, D.G. and Jahns, H.M.''' 2005.

ISBN 0 521 30419 9</ref> ===Modern botany=== A considerable amount of new knowledge today is being generated from studying [[model organisms|model plants]] like ''[[Arabidopsis thaliana]]''. This weedy species in the mustard family was one of the first plants to have its [[genome]] sequenced. The sequencing of the [[rice]] (''Oryza sativa'') genome and a large international research community have made [[rice]] the de facto [[cereal]]/[[grass]]/[[monocot]] model. Another grass species, ''[[Brachypodium distachyon]]'' is also emerging as an experimental model for understanding the genetic, cellular and molecular biology of temperate grasses. Other commercially-important staple foods like [[wheat]], [[maize]], [[barley]], [[rye]], [[pearl millet]] and [[soybean]] are also having their genomes sequenced. Some of these are challenging to sequence because they have more than two [[haploid]] (n) sets of [[chromosome]]s, a condition known as [[polyploid]]y, common in the plant kingdom. ''[[Chlamydomonas reinhardtii]]'' (a single-celled, green [[Algae|alga]]) is another plant model organism that has been extensively studied and provided important insights into cell biology. In 1998 the [[Angiosperm Phylogeny Group]] published a [[phylogeny]] of flowering plants based on an analysis of [[DNA]] sequences from most families of flowering plants. As a result of this work, major questions such as which families represent the earliest branches in the genealogy of [[angiosperms]] are now understood. Investigating how plant species are related to each other allows botanists to better understand the process of evolution in plants. ==Subdisciplines of Botany== *[[Agronomy]]—Application of plant science to crop production *[[Bryology]]—Mosses, liverworts, and hornworts *[[Economic botany]]—The place of plants in economics *[[Ethnobotany]]—Relationship between humans and plants *[[Forestry]]—Forest management and related studies *[[Horticulture]]—Cultivated plants *[[Paleobotany]]—Fossil plants *[[Palynology]]—Pollen and spores *[[Phycology]] - Algae *[[Phytochemistry]]—Plant secondary chemistry and chemical processes *[[Phytopathology]]—Plant diseases *[[Plant anatomy]]—Cell and tissue structure *[[Plant ecology]]—Role of plants in the environment *Plant genetics—Genetic inheritance in plants *[[Plant morphology]]—Structure and life cycles *[[Plant physiology]]—Life functions of plants *[[Plant taxonomy|Plant systematics]]—Classification and naming of plants ==Notable Botanists== *[[Ibn al-Baitar]] (d. 1248), Andalusian-Arab scientist, botanist, pharmacist, physician, and author of one of the largest botanical encyclopedias. *[[Al-Dinawari]] (828-896), Kurdish botanist, historian, geographer, astronomer, mathematician, and founder of [[Muslim Agricultural Revolution#Agricultural sciences|Arabic botany]]. *[[Luther Burbank]] (1849-1926), American botanist, horticulturist, and a pioneer in agricultural science. *[[Joseph Dalton Hooker]] (1817-1911), English botanist and explorer.
