Guidance on how to use these products.Botany Wikipedia.Botany, also called plant sciences, plant biology or phytology, is the science of plant life and a branch of biology.A botanist or plant scientist is a scientist who specialises in this field.The term botany comes from the Ancient Greek word botan meaning pasture, grass, or fodder is in turn derived from boskein, to feed or to graze.When time and funding permit, each flower each plant species will have its own page, and its own PDF, and eventually its own PPT so that professors and students.June 3, Nathan Rabin, TV Review THE SIMPSONS CLASSIC Mr.Plow season 4, episode 9 originally aired 11191992, in Please provide.Dear students if you are looking for Lucknow University Syllabus 2017, you are welcome on this page.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 4.Botany originated in prehistory as herbalism with the efforts of early humans to identify and later cultivate edible, medicinal and poisonous plants, making it one of the oldest branches of science.Medieval physic gardens, often attached to monasteries, contained plants of medical importance.They were forerunners of the first botanical gardens attached to universities, founded from the 1.One of 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 1.Carl Linnaeus that remains in use to this day.In the 1. 9th and 2.In the last two decades of the 2.DNA sequences to classify plants more accurately.Modern botany is a broad, multidisciplinary subject with inputs from most other areas of science and technology.Botany In A Day Pdf Download' title='Botany In A Day Pdf Download' />Research topics include the study of plant structure, growth and differentiation, reproduction, biochemistry and primary metabolism, chemical products, development, diseases, evolutionary relationships, systematics, and plant taxonomy.Dominant themes in 2.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 the maintenance of biodiversity.HistoryeditEarly botanyeditBotany originated as herbalism, the study and use of plants for their medicinal properties.Many records of the Holocene period date early botanical knowledge as far back as 1.This early unrecorded knowledge of plants was discovered in ancient sites of human occupation within Tennessee, which make up much of the Cherokee land today.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 1.BC, in archaic Avestan writings, and in works from China before it was unified in 2.BC. Modern botany traces its roots back to Ancient Greece specifically to Theophrastus c.BC, a student of Aristotle who invented and described many of its principles and is widely regarded in the scientific community as the Father of Botany.His major works, Enquiry into Plants and On the Causes of Plants, constitute the most important contributions to botanical science until the Middle Ages, almost seventeen centuries later.Another work from Ancient Greece that made an early impact on botany is De Materia Medica, a five volume encyclopedia about herbal medicine written in the middle of the first century by Greek physician and pharmacologist Pedanius Dioscorides.De Materia Medica was widely read for more than 1,5.Important contributions from the medieval Muslim world include Ibn Wahshiyyas Nabatean Agriculture, Ab anfa Dnawars 8.Book of Plants, and Ibn Bassals The Classification of Soils.In the early 1. 3th century, Abu al Abbas al Nabati, and Ibn al Baitar d.In the mid 1. 6th century, botanical gardens were founded in a number of Italian universities the Padua botanical garden in 1.These gardens continued the practical value of earlier physic gardens, often associated with monasteries, in which plants were cultivated for medical use.They supported the growth of botany as an academic subject.Lectures were given about the plants grown in the gardens and their medical uses demonstrated.Botanical gardens came much later to northern Europe the first in England was the University of Oxford Botanic Garden in 1.Throughout this period, botany remained firmly subordinate to medicine.German physician Leonhart Fuchs 1.German fathers of botany, along with theologian Otto Brunfels 1.Hieronymus Bock 1.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 1.Historia Plantarum in 1.Dispensatorium in 1.Naturalist Conrad von Gesner 1.John Gerard 1. 54.Naturalist Ulisse Aldrovandi 1.In 1. 66. 5, using an early microscope, Polymath.Robert Hooke discovered cells, a term he coined, in cork, and a short time later in living plant tissue.Early modern botanyedit.The Linnaean Garden of Linnaeus residence in Uppsala, Sweden, was planted according to his Systema sexuale.During the 1. 8th century, systems of plant identification were developed comparable to dichotomous keys, where unidentified plants are placed into taxonomic groups e.The choice and sequence of the characters may be artificial in keys designed purely for identification diagnostic keys or more closely related to the natural or phyletic order of the taxa in synoptic keys.By the 1. 8th century, new plants for study were arriving in Europe in increasing numbers from newly discovered countries and the European colonies worldwide.In 1. 75. 3 Carl von Linn Carl Linnaeus published his Species Plantarum, a hierarchical classification of plant species that remains the reference point for modern botanical nomenclature.This established a standardised binomial or two part naming scheme where the first name represented the genus and the second identified the species within the genus.For the purposes of identification, Linnaeuss Systema Sexualeclassified plants into 2.The 2. 4th group, Cryptogamia, included all plants with concealed reproductive parts, mosses, liverworts, ferns, algae and fungi.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 1. 76. 3, de Jussieu 1.Candolle 1. 81. 9 all proposed various alternative natural systems of classification that grouped plants using a wider range of shared characters and were widely followed.The Candollean system reflected his ideas of the progression of morphological complexity and the later classification by Bentham and Hooker, which was influential until the mid 1.Candolles approach.Darwins publication of the Origin of Species in 1.Candollean system to reflect evolutionary relationships as distinct from mere morphological similarity.Botany was greatly stimulated by the appearance of the first modern textbook, Matthias Schleidens Grundzge der Wissenschaftlichen Botanik, published in English in 1.Principles of Scientific Botany.Schleiden was a microscopist and an early plant anatomist who co founded the cell theory with Theodor Schwann and Rudolf Virchow and was among the first to grasp the significance of the cell nucleus that had been described by Robert Brown in 1.In 1. 85. 5, Adolf Fick formulated Ficks laws that enabled the calculation of the rates of molecular diffusion in biological systems.Echeveria glauca in a Connecticut greenhouse.Botany uses Latin names for identification, here, the specific name glauca means blue.Late modern botanyedit.Micropropagation of transgenic plants.Building upon the gene chromosome theory of heredity that originated with Gregor Mendel 1.August Weismann 1.No other cells can pass on inherited characters.The work of Katherine Esau 1.Her books Plant Anatomy and Anatomy of Seed Plants have been key plant structural biology texts for more than half a century.The discipline of plant ecology was pioneered in the late 1.Eugenius Warming, who produced the hypothesis that plants form communities, and his mentor and successor Christen C.Raunkir whose system for describing plant life forms is still in use today.
