Who is schwann and schleiden

Nevertheless, his work gave biologists their first insight into the most basic structure of all living organisms. In preparing his theory, Schleiden had consulted his friend the German physiologist Theodor Schwann —82 , and the following year, , Schwann extended the cell theory to animals, in Mikroskopische Untersuchungen uber die Ubereinstimmung in der Struktur und dem Wachstum der Tiere und Pflanzen Microscopical researches into the agreement between the structure and growth of animals and plants.

Schleiden and Schwann are jointly credited with having originated the cell theory. Schwann was also the first scientist to observe that an egg begins as a single cell and develops into a complex organism by repeated cell division. Matthias Jakob Schleiden was born in Hamburg on April 5, In he entered the University of Heidelburg to study law. He graduated in , and for a time he practiced law in Hamburg, but then turned to botany and medicine, which he studied at the universities of Gottingen, Berlin, and Jena, finally graduating in After graduating Schleiden was appointed professor of botany at Jena, where he remained until , when he became professor of botany at the University of Dorpat, Estonia.

In he returned to Germany and began teaching privately in Frankfurt-am-Main, where he died on June 23, After the Russian government granted him a pension, Schleiden became a Privatgelehrter , a private scholar, and frequently moved from city to city.

Schleiden and Schwann proposed spontaneous generation as the method for cell origination, but spontaneous generation also called abiogenesis was later disproven. The generally accepted portions of the modern Cell Theory are as follows:.

Learning Objectives Identify the components of cell theory. Key Points The cell theory describes the basic properties of all cells. The three scientists that contributed to the development of cell theory are Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. A component of the cell theory is that all living things are composed of one or more cells.

A component of the cell theory is that the cell is the basic unit of life.
