Rudolf Virchow later made important contributions to this theory.
The cell theory defined the cell as the base unit of all living organisms, and had great influence on the study of both plants and animals.

Among other things, Schwann is known for recognising that the ...

The second part states that cells are the basic units of life. These parts were based on a conclusion made by Schwann and Matthias Schleiden in 1838, after comparing their ...
Schleiden and Schwann first proposed the cell theory, which was later modified by Rudolf Virchow. Since the discovery of the first cells, cell theory has evolved and grown, and many amazing experiments have been designed to demonstrate its many components. Parts of Cell Theory. There are three main postulates of cell theory are as follows:
Jan 24, 2020 · Cell Theory is one of the basic principles of biology. Credit for the formulation of this theory is given to German scientists Theodor Schwann (1810–1882), Matthias Schleiden (1804–1881), and Rudolph Virchow (1821–1902). The Cell Theory states: All living organisms are composed of cells. They may be unicellular or multicellular.
