Cell theory



The scientific theory describing cells, e.g. the cell as the basic unit of living organisms, and that all cells arise only from pre-existing, living cells


The basic tenets of the cell theory are as follows:

The cell theory is credited to the scientists, particularly, Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow. Theodor Schwann, a German physiologist, stated in his writings that all living things are composed of cells and the products of cells in their structures.1 This theory was founded together with M. J. Schleiden, a German botanist. Rudolf Virchow, a German biologist and doctor, contributed to the cell theory with his tenet in Latin: "Omnis cellula e cellula", which translates to "All things arise from pre-existing cells".2 This tenet negates the theory of spontaneous generation.
