Regions with characteristic vegetation types and dominant plants as well as similar abiotic and biotic factors, climate , and geography make up biomes like tundra or tropical rainforest . Herbivores eat plants, but plants can defend themselves and some species are parasitic or even carnivorous . Other organisms form mutually beneficial relationships with plants. For example, mycorrhizal fungi and rhizobia provide plants with nutrients in exchange for food, ants are recruited by ant plants to provide protection, honey bees , bats and other animals pollinate flowers and humans and other animals act as dispersal vectors to spread spores and seeds . Plant responses to climate and other environmental changes can inform our understanding of how these changes affect ecosystem function and productivity. For example, plant phenology can be

The goals of plant ecology are to understand the causes of their distribution patterns, productivity, environmental impact, evolution, and responses to environmental change. Plants depend on certain edaphic (soil) and climatic factors in their environment but can modify these factors too. For example, they can change their environment's albedo , increase runoff interception, stabilise mineral soils and develop their organic content, and affect local temperature. Plants compete with other organisms in their ecosystem for resources. They interact with their neighbours at

Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress . Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants , including some 391,000 species of vascular plants (of which approximately 369,000 are flowering plants ) and approximately 20,000 bryophytes . Botany originated in prehistory as herbalism with

The journey conclusively disproved the Terra Australis Incognita theory, which claimed there was a big, habitable continent in the South. Supervised by his father, Georg Forster first undertook studies of the zoology and botanics of the southern seas, mostly by drawing animals and plants. However, Georg also pursued his own interests, which led to completely independent explorations in comparative geography and ethnology . He quickly learned
5760-466: The Pacific . His report of that journey, A Voyage Round the World , contributed significantly to the ethnology of the people of Polynesia and remains a respected work. As a result of the report, Forster, who was admitted to the Royal Society at the early age of twenty-two, came to be considered one of the founders of modern scientific travel literature. After returning to continental Europe, Forster turned toward academia. He taught natural history at

In contrast to the attitude expressed in these writings and to his Enlightenment background, he used insulting terms expressing prejudice against Poles in his private letters during his stay in Vilnius and in
9600-461: The developing diploid embryo sporophyte within its tissues for at least part of its life, even in the seed plants, where the gametophyte itself is nurtured by its parent sporophyte. Other groups of organisms that were previously studied by botanists include bacteria (now studied in bacteriology ), fungi ( mycology ) – including lichen -forming fungi ( lichenology ), non- chlorophyte algae ( phycology ), and viruses ( virology ). However, attention
9728-459: The earliest was the Padua botanical garden . These gardens facilitated the academic study of plants. Efforts to catalogue and describe their collections were the beginnings of plant taxonomy and led in 1753 to the binomial system of nomenclature of Carl Linnaeus that remains in use to this day for the naming of all biological species. In the 19th and 20th centuries, new techniques were developed for
9856-402: The earth have equal claims to my good will ... and my praise and blame are independent of national prejudice. In his opinion all human beings have the same abilities with regard to reason, feelings and imagination, but these basic ingredients are used in different ways and in different environments, which gives rise to different cultures and civilizations. According to him it is obvious that
9984-419: The efforts of early humans to identify – and later cultivate – plants that were edible, poisonous, and possibly medicinal, making it one of the first endeavours of human investigation. Medieval physic gardens , often attached to monasteries , contained plants possibly having medicinal benefit. They were forerunners of the first botanical gardens attached to universities , founded from the 1540s onwards. One of
10112-453: The extensive earlier work of Alphonse de Candolle , Nikolai Vavilov (1887–1943) produced accounts of the biogeography , centres of origin , and evolutionary history of economic plants. Particularly since the mid-1960s there have been advances in understanding of the physics of plant physiological processes such as transpiration (the transport of water within plant tissues), the temperature dependence of rates of water evaporation from
10240-612: The first and most outstanding German ethnologists is indisputable, and his works are seen as crucial in the development of ethnology in Germany into a separate branch of science. The ethnographical items collected by Georg and Johann Reinhold Forster are now presented as the Cook-Forster-Sammlung (Cook–Forster Collection) in the Sammlung für Völkerkunde anthropological collection in Göttingen . Another collection of items collected by
10368-732: The first independent female writers in Germany. . From his time in Kassel on, Forster actively corresponded with important figures of the Enlightenment , including Lessing , Herder , Wieland and Goethe . He also initiated cooperation between the Carolinum in Kassel and the University of Göttingen where his friend Georg Christoph Lichtenberg worked. Together, they founded and published the scientific and literary journal Göttingisches Magazin der Wissenschaften und Litteratur . Forster's closest friend, Samuel Thomas von Sömmering , arrived in Kassel shortly after Forster, and both were soon involved with
10496-563: The fossil record. It is widely regarded as a marker for the start of land plant evolution during the Ordovician period. The concentration of carbon dioxide in the atmosphere today is much lower than it was when plants emerged onto land during the Ordovician and Silurian periods. Many monocots like maize and the pineapple and some dicots like the Asteraceae have since independently evolved pathways like Crassulacean acid metabolism and
10624-451: The functional relationships between plants and their habitats – the environments where they complete their life cycles . Plant ecologists study the composition of local and regional floras , their biodiversity , genetic diversity and fitness , the adaptation of plants to their environment, and their competitive or mutualistic interactions with other species. Some ecologists even rely on empirical data from indigenous people that
10752-444: The global carbon and water cycles and plant roots bind and stabilise soils, preventing soil erosion . Plants are crucial to the future of human society as they provide food, oxygen, biochemicals , and products for people, as well as creating and preserving soil. Historically, all living things were classified as either animals or plants and botany covered the study of all organisms not considered animals. Botanists examine both
10880-621: The important botanical questions of the 21st century are the role of plants as primary producers in the global cycling of life's basic ingredients: energy, carbon, oxygen, nitrogen and water, and ways that our plant stewardship can help address the global environmental issues of resource management , conservation , human food security , biologically invasive organisms , carbon sequestration , climate change , and sustainability . Virtually all staple foods come either directly from primary production by plants, or indirectly from animals that eat them. Plants and other photosynthetic organisms are at
11008-504: The inhabitants of the Nomuka islands (in the Ha'apai island group of present-day Tonga), he wrote that their languages, vehicles, weapons, furniture, clothes, tattoos, style of beard, in short all of their being matched perfectly with what he had already seen while studying tribes on Tongatapu . However, he wrote, "we could not observe any subordination among them, though this had strongly characterised
11136-478: The internal functions and processes within plant organelles , cells, tissues, whole plants, plant populations and plant communities. At each of these levels, a botanist may be concerned with the classification ( taxonomy ), phylogeny and evolution , structure ( anatomy and morphology ), or function ( physiology ) of plant life. The strictest definition of "plant" includes only the "land plants" or embryophytes , which include seed plants (gymnosperms, including
11264-461: The languages of the Polynesian islands. His reports on the people of Polynesia are well regarded today, as they describe the inhabitants of the southern islands with empathy, sympathy and largely without Western or Christian bias. Unlike Louis Antoine de Bougainville , whose reports from a journey to Tahiti a few years earlier had initiated uncritical noble savage romanticism, Forster developed
11392-403: The leaf shapes and sizes of ancient land plants . Ozone depletion can expose plants to higher levels of ultraviolet radiation-B (UV-B), resulting in lower growth rates. Moreover, information from studies of community ecology , plant systematics , and taxonomy is essential to understanding vegetation change , habitat destruction and species extinction . Inheritance in plants follows
11520-576: The leaf surface and the molecular diffusion of water vapour and carbon dioxide through stomatal apertures. These developments, coupled with new methods for measuring the size of stomatal apertures, and the rate of photosynthesis have enabled precise description of the rates of gas exchange between plants and the atmosphere. Innovations in statistical analysis by Ronald Fisher , Frank Yates and others at Rothamsted Experimental Station facilitated rational experimental design and data analysis in botanical research. The discovery and identification of
11648-576: The maintenance of biodiversity . Botany originated as herbalism , the study and use of plants for their possible medicinal properties . The early recorded history of botany includes many ancient writings and plant classifications. Examples of early botanical works have been found in ancient texts from India dating back to before 1100 BCE, Ancient Egypt , in archaic Avestan writings, and in works from China purportedly from before 221 BCE. Modern botany traces its roots back to Ancient Greece specifically to Theophrastus ( c. 371 –287 BCE),
11776-493: The major groups of organisms that carry out photosynthesis , a process that uses the energy of sunlight to convert water and carbon dioxide into sugars that can be used both as a source of chemical energy and of organic molecules that are used in the structural components of cells. As a by-product of photosynthesis, plants release oxygen into the atmosphere, a gas that is required by nearly all living things to carry out cellular respiration. In addition, they are influential in
11904-474: The mechanisms and control of gene expression during differentiation of plant cells and tissues . Botanical research has diverse applications in providing staple foods , materials such as timber , oil , rubber, fibre and drugs, in modern horticulture , agriculture and forestry , plant propagation , breeding and genetic modification , in the synthesis of chemicals and raw materials for construction and energy production, in environmental management , and
12032-437: The most important journey descriptions ever written. The book also had a significant impact on German literature, culture and science, influencing such scientists as Alexander von Humboldt and it inspired many ethnologists of later times. Forster wrote well-polished German prose, which was not only scientifically accurate and objective, but also exciting and easy to read. This differed from conventional travel literature of
12160-459: The natives of Tonga-Tabboo, who seemed to descend even to servility in their obeisance to the king." The journey was rich in scientific results. However, the relationship between the Forsters and Cook and his officers was often problematic, due to the elder Forster's fractious temperament as well as Cook's refusal to allow more time for botanical and other scientific observation. Cook refused scientists on his third journey after his experiences with
12288-596: The number of their male sexual organs. The 24th group, Cryptogamia , included all plants with concealed reproductive parts, mosses , liverworts , ferns , algae and fungi . Botany was originally a hobby for upper-class women. These women would collect and paint flowers and plants from around the world with scientific accuracy. The paintings were used to record many species that could not be transported or maintained in other environments. Marianne North illustrated over 900 species in extreme detail with watercolor and oil paintings. Her work and many other women's botany work
12416-447: The other hand with medicine and pharmacology, giving rise to fields such as agronomy , horticultural botany, phytopathology and phytopharmacology . The study of plants is vital because they underpin almost all animal life on Earth by generating a large proportion of the oxygen and food that provide humans and other organisms with aerobic respiration with the chemical energy they need to exist. Plants, algae and cyanobacteria are
12544-404: The outcome of prehistoric selection over thousands of years from among wild ancestral plants with the most desirable characteristics. Botanists study how plants produce food and how to increase yields, for example through plant breeding , making their work important to humanity's ability to feed the world and provide food security for future generations. Botanists also study weeds, which are
12672-791: The pain killer aspirin is the acetyl ester of salicylic acid , originally isolated from the bark of willow trees, and a wide range of opiate painkillers like heroin are obtained by chemical modification of morphine obtained from the opium poppy . Popular stimulants come from plants, such as caffeine from coffee, tea and chocolate, and nicotine from tobacco. Most alcoholic beverages come from fermentation of carbohydrate -rich plant products such as barley (beer), rice ( sake ) and grapes (wine). Native Americans have used various plants as ways of treating illness or disease for thousands of years. This knowledge Native Americans have on plants has been recorded by enthnobotanists and then in turn has been used by pharmaceutical companies as
12800-479: The plants with a highly fermentable sugar or oil content that are used as sources of biofuels , important alternatives to fossil fuels , such as biodiesel . Sweetgrass was used by Native Americans to ward off bugs like mosquitoes . These bug repelling properties of sweetgrass were later found by the American Chemical Society in the molecules phytol and coumarin . Plant ecology is the science of
12928-524: The politics of the times, with different periods focusing on different parts of his work. In the period of rising nationalism after the Napoleonic era he was regarded in Germany as a "traitor to his country", overshadowing his work as an author and scientist. This attitude rose even though the philosopher Karl Wilhelm Friedrich Schlegel wrote about Forster at the beginning of the 19th century: Among all those authors of prose who are justified in laying claim to
13056-486: The pollen either fails to reach the stigma or fails to germinate and produce male gametes . This is one of several methods used by plants to promote outcrossing . In many land plants the male and female gametes are produced by separate individuals. These species are said to be dioecious when referring to vascular plant sporophytes and dioicous when referring to bryophyte gametophytes . Charles Darwin in his 1878 book The Effects of Cross and Self-Fertilization in
13184-442: The polymer cutin which is found in the plant cuticle that protects land plants from drying out. Plants synthesise a number of unique polymers like the polysaccharide molecules cellulose , pectin and xyloglucan from which the land plant cell wall is constructed. Vascular land plants make lignin , a polymer used to strengthen the secondary cell walls of xylem tracheids and vessels to keep them from collapsing when
13312-443: The practical value of earlier "physic gardens", often associated with monasteries, in which plants were cultivated for suspected medicinal uses. They supported the growth of botany as an academic subject. Lectures were given about the plants grown in the gardens. Botanical gardens came much later to northern Europe; the first in England was the University of Oxford Botanic Garden in 1621. German physician Leonhart Fuchs (1501–1566)
13440-527: The press finally reigns within these walls where the printing press was invented. This freedom did not last long, though. The Mainz Republic existed only until the retreat of the French troops in July 1793 after the siege of Mainz . Forster was not present in Mainz during the siege. As representatives of the Mainz National Convention, he and Adam Lux had been sent to Paris to apply for Mainz – which
13568-519: The pressure of the terror. He viewed the events in France as a force of nature that could not be slowed and that had to release its own energies to avoid being even more destructive. Before the reign of terror reached its climax, Forster died after a rheumatic illness in his small attic apartment at Rue des Moulins in Paris on 10 January 1794, at the age of thirty-nine. At the time, he was making plans to visit India. Forster had partial Scottish roots and
13696-625: The republic's temporary administration and a candidate in the elections to the local parliament, the Rheinisch-Deutscher Nationalkonvent ( Rhenish-German National Convention ). From January to March 1793, he was an editor of Die neue Mainzer Zeitung oder Der Volksfreund ( The new Mainz newspaper or The People's Friend ), a name chosen in reference to Marat 's L'Ami du peuple . In his first article he wrote: Die Pressefreiheit herrscht endlich innerhalb dieser Mauern, wo die Buchdruckerpresse erfunden ward. The freedom of
13824-461: The rise of the related molecular-scale biological approaches of molecular biology , genomics , proteomics and metabolomics , the relationship between the plant genome and most aspects of the biochemistry, physiology, morphology and behaviour of plants can be subjected to detailed experimental analysis. The concept originally stated by Gottlieb Haberlandt in 1902 that all plant cells are totipotent and can be grown in vitro ultimately enabled
13952-676: The same fundamental principles of genetics as in other multicellular organisms. Gregor Mendel discovered the genetic laws of inheritance by studying inherited traits such as shape in Pisum sativum ( peas ). What Mendel learned from studying plants has had far-reaching benefits outside of botany. Similarly, " jumping genes " were discovered by Barbara McClintock while she was studying maize. Nevertheless, there are some distinctive genetic differences between plants and other organisms. Species boundaries in plants may be weaker than in animals, and cross species hybrids are often possible. A familiar example
14080-450: The study of plants, including methods of optical microscopy and live cell imaging , electron microscopy , analysis of chromosome number , plant chemistry and the structure and function of enzymes and other proteins . In the last two decades of the 20th century, botanists exploited the techniques of molecular genetic analysis , including genomics and proteomics and DNA sequences to classify plants more accurately. Modern botany
14208-471: The study of plants. In 1665, using an early microscope, Polymath Robert Hooke discovered cells (a term he coined) in cork , and a short time later in living plant tissue. During the 18th century, systems of plant identification were developed comparable to dichotomous keys , where unidentified plants are placed into taxonomic groups (e.g. family, genus and species) by making a series of choices between pairs of characters . The choice and sequence of
14336-459: The time, insofar as it presented more than a mere collection of data – it also demonstrated coherent, colourful and reliable ethnographical facts that resulted from detailed and sympathetic observation. He often interrupted the description to enrich it with philosophical remarks about his observations. His main focus was always on the people he encountered: their behavior, customs, habits, religions and forms of social organization. In A Voyage Round
14464-526: The use of genetic engineering experimentally to knock out a gene or genes responsible for a specific trait, or to add genes such as GFP that report when a gene of interest is being expressed. These technologies enable the biotechnological use of whole plants or plant cell cultures grown in bioreactors to synthesise pesticides , antibiotics or other pharmaceuticals , as well as the practical application of genetically modified crops designed for traits such as improved yield. Modern morphology recognises
14592-485: The word plant (e.g. plant taxonomy, plant ecology, plant anatomy, plant morphology, plant systematics, plant ecology), or prefixing or substituting the prefix phyto- (e.g. phytochemistry , phytogeography ). The study of fossil plants is palaeobotany . Other fields are denoted by adding or substituting the word botany (e.g. systematic botany ). Phytosociology is a subfield of plant ecology that classifies and studies communities of plants. The intersection of fields from
14720-485: Was indology – one of the main goals of his failed expedition to be financed by Catherine II had been to reach India. He translated the Sanskrit play Shakuntala using a Latin version provided by Sir William Jones ; this strongly influenced Johann Gottfried Herder , and triggered German interest in the culture of India. In the second quarter of 1790, Forster and the young Alexander von Humboldt started from Mainz on
14848-409: Was a central figure of the Enlightenment in Germany, and corresponded with most of its adherents, including his close friend Georg Christoph Lichtenberg . His ideas, travelogues and personality influenced Alexander von Humboldt , one of the great scientists of the 19th century who hailed Forster as the founder of both comparative ethnology ( Völkerkunde ) and regional geography ( Länderkunde ). When
14976-452: Was accepted well in Vilnius , but he felt more and more isolated with time. Most of his contacts were still with scientists in Germany; especially notable is his dispute with Immanuel Kant about the definition of race . In 1785, Forster traveled to Halle where he submitted his thesis on the plants of the South Pacific for a doctorate in medicine. Back in Vilnius, Forster's ambitions to build
15104-588: Was born in Polish Royal Prussia , and therefore was by birth a Polish subject. He worked in Russia, England, Poland and in several German countries of his time. Finally, he finished his life in France. He worked in different milieus and traveled a lot from his youth on. It was his view that this, together with his scientific upbringing based on the principles of the Enlightenment, gave him a wide perspective on different ethnic and national communities: All peoples of
15232-745: Was in contact with Sir Joseph Banks , the initiator of the Bounty expedition and a participant in Cook's first journey. While at the University of Vilnius he wrote the article "Neuholland und die brittische Colonie in Botany-Bay", published in the Allgemeines historisches Taschenbuch (Berlin, December 1786), an essay on the future prospects of the English colony founded in New South Wales in 1788. Another interest of his
15360-483: Was interested in the study of nature, and his father first learned natural history from the books of Carl Linnaeus and then taught his son biology as well as Latin, French, and religion. In 1765, Reinhold obtained a commission by the Russian government to inspect the recently founded colonies near Saratov on the Volga River , which were mostly settled by German colonists . Ten-year old Georg accompanied his father on
15488-470: Was often taken at face value in Imperial and Nazi Germany, where it was used as a means of science-based support for a purported German superiority. The spreading of the "Polnische Wirtschaft" (Polish economy) stereotype is most likely due to the influence of his letters. Forster's attitude brought him into conflict with the people of the different nations he encountered and made him welcome nowhere, as he
15616-399: Was one of "the three German fathers of botany", along with theologian Otto Brunfels (1489–1534) and physician Hieronymus Bock (1498–1554) (also called Hieronymus Tragus). Fuchs and Brunfels broke away from the tradition of copying earlier works to make original observations of their own. Bock created his own system of plant classification. Physician Valerius Cordus (1515–1544) authored
15744-455: Was published. This report was the first account of Cook's second voyage (it appeared six weeks before the official publication) and was intended for the general public. The English version and his own translation into German (published 1778–80) earned the young author real fame. The poet Christoph Martin Wieland praised the book as the most important one of his time, and even today it remains one of
15872-412: Was the beginning of popularizing botany to a wider audience. Increasing knowledge of plant anatomy , morphology and life cycles led to the realisation that there were more natural affinities between plants than the artificial sexual system of Linnaeus. Adanson (1763), de Jussieu (1789), and Candolle (1819) all proposed various alternative natural systems of classification that grouped plants using
16000-697: Was to be published after their return. They embarked HMS Resolution on 13 July 1772, in Plymouth . The ship's route led first to the South Atlantic , then through the Indian Ocean and the Southern Ocean to the islands of Polynesia and finally around Cape Horn back to England, returning on 30 July 1775. During the three-year journey, the explorers visited New Zealand, the Tonga islands, New Caledonia , Tahiti ,
16128-410: Was too revolutionary and antinational for Germans, proud and opposing in his dealings with Englishmen, too unconcerned about Polish science for Poles, and too insignificant politically and ignored while in France. After Forster's death, his works were mostly forgotten, except in professional circles. This was partly due to his involvement in the French revolution. However, his reception changed with
16256-468: Was unable to exist as an independent state – to become a part of the French Republic . The application was accepted, but had no effect, since Mainz was conquered by Prussian and Austrian troops, and the old order was restored. Forster lost his library and collections and decided to remain in Paris. Based on a decree by Emperor Francis II inflicting punishments on German subjects who collaborated with
16384-591: Was widely perceived as "barbarian" at that time. The book conformed well to the early Romantic intellectual movements in German-speaking Europe. Forster's main interest, however, was again focused on the social behavior of people, as 15 years earlier in the Pacific. The national uprisings in Flanders and Brabant and the revolution in France sparked his curiosity. The journey through these regions, together with
