Encyclopedia > Plant anatomy

Plant anatomy or phytotomy is the general term for the study of the structure of plants. However, the description of the external stucture plants is often called plant morphology, hence the term plant anatomy is sometimes reserved for the internal structure of plants. Plant morphology is generally used in the field identification of plants. Plant anatomy is now frequently investigated at the cellular level.

History

About 300 BCE Theophrastus wrote a number of plant treatises, only two of which survive. He developed concepts of plant morphology and classification, which did not withstand the scientific scrutiny of the Renaissance. Theophrastus (Greek Θεόφραστος, 370 — about 285 BC), a native of Eressos in Lesbos, was the successor of Aristotle in the Peripatetic school. ... For other uses, see Renaissance (disambiguation). ...


A Swiss physician and botanist, Gaspard Bauhin, introduced binomial nomenclature into plant taxonomy. He published Pinax theatri botanici in 1596, which was the first to use this convention for naming of species. His criteria for classification included natural relationships, or 'affinities', which in many cases were structural. Gaspard Bauhin Gaspard Bauhin, or Caspar Bauhin (January 17, 1560 – December 5, 1624), was a Swiss-French botanist. ... In biology, binomial nomenclature is the formal method of naming species. ...

Italian doctor and microscopist, Marcello Malpighi, was one of the two founders of plant anatomy. In 1671 he published his Anatomia Plantarum, the first major advance in plant physiogamy since Aristotle. Marcello Malpighi (March 10, 1628 - November 29, 1694) was an Italian doctor, who gave his name to several physiological features. ...


The British doctor, Nehemiah Grew was one of the two founders of plant anatomy. He published An Idea of a Philosophical History of Plants in 1672 and The Anatomy of Plants in 1682. Grew is credited with the recognition of plant cells, although he called them 'vesicles' and 'bladders'. He correctly identified and described the sexual organs of plants (flowers) and their parts.

In the Eighteenth Century, Carolus Linnaeus established taxonomy based on structure, and his early work was with plant anatomy. While the exact structural level which is to be considered to be scientifically valid for comparison and differentiation has changed with the growth of knowledge, the basic principles were established by Linnaeus. He published his master work, Species Plantarum in 1753. Carolus Linnaeus, also known after his ennoblement as  , (May 23, 1707 – January 10, 1778), was a Swedish botanist, physician and zoologist[1] who laid the foundations for the modern scheme of nomenclature. ...


In 1802, French botanist, Charles-François Brisseau de Mirbel, published Traité d'anatomie et de physiologie végétale (Treatise on Plant Anatomy and Physiolog) establishing the beginnings of the science of plant cytology.

Cell biology (also called cellular biology or formerly cytology, from the Greek kytos, container) is an academic discipline that studies cells. ...


In 1813 a Swiss botanist, Augustin Pyrame de Candolle, published Théorie élémentaire de la botanique, in which he argued that plant anatomy, not physiology, ought to be the sole basis for plant classification. Using a scientific basis, he established structural criteria for defining and separating plant genera. A. P. de Candolle A. P. de Candolle (February 4, 1778 - September 9, 1841) was one of the great botanists of all time. ...

A German-Polish botanist, Eduard Strasburger, described the mitotic process in plant cells and further demonstrated that new cell nuclei can only arise from the division of other pre-existing nuclei. His Studien über Protoplasma was published in 1876. Eduard Adolf Strasburger (February 1, 1844, Warsaw - May 19, 1912, Bonn) was one of the most famous German botanists of the 19th century. ...


Gottlieb Haberlandt, a German botanist, studied plant physiology and classified plant tissue based upon function. On this basis, in 1884 he published Physiologische Pflanzenanatomie (Physiological Plant Anatomy) in which he described twelve types of tissue systems (absorptive, mechanical, photosynthetic, etc.). Gottlieb Haberlandt (28 November 1854 to 30 January 1945) was a Austrian botanist. ...

Scott's Studies in Fossil Botany was published in 1900. William Crawford Williamson (November 24, 1816-June 23, 1895) was an English naturalist. ...


Following Charles Darwin's Origen of Species a Canadian botanist, Edward Charles Jeffrey, who was studing the comparative anatomy and phylogeny of different vascular plant groups, applied the theory to plants using the form and structure of plants to establish a number of evolutionary lines. He published his The Anatomy of Woody Plants in 1917. Charles Robert Darwin FRS (12 February 1809 – 19 April 1882) was an English naturalist [1] who achieved lasting fame by producing considerable evidence that species originated through evolutionary change, at the same time proposing the scientific theory that natural selection is the mechanism by which such change occurs. ...


The growth of comparative plant anatomy was spearheaded by a British botanist, Agnes Arber. She published Water Plants: A Study of Aquatic Angiosperms in 1920, Monocotyledons: A Morphological Study in 1925, and The Gramineae: A Study of Cereal, Bamboo and Grass in 1934. Agnes Arber (1879-1960) was a renowned British plant morphologist and anatomist, historian of botany and philosopher of biology. ...


Following World War II, Katherine Esau published, Plant Anatomy (1953), which became the definitive textbook on plant structure in North American universities and elsewhere, it was still in print as of 2006. She followed up with her Anatomy of seed plants in 1960.

Anatomy - Wikipedia, the free encyclopedia (525 words)
Anatomy (from the Greek anatome, from ana-temnein, to cut up), is the branch of biology that deals with the structure and organization of living things.
Animal anatomy may include the study of the structure of different animals, when it is called comparative anatomy or animal morphology, or it may be limited to one animal only, in which case it is spoken of as special anatomy.
From the morphological point of view, however, human anatomy is a scientific and fascinating study, having for its object the discovery of the causes which have brought about the existing structure of humans, and needing a knowledge of the allied sciences of embryology or developmental biology, phylogeny, and histology.
