the beginning of the cell theory
The cell theory says that all organisms are made up of similar units of organization, called cells. The concept was formally articulated in 1839 by Matthis Scheiden and Theodor Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin's theory of evolution (1859), Mendel's laws of inheritance (1865), and the establishment of comparative biochemistry (1940).

2. All living cells rise from cells before them, by division.
3. The cell is a basic unit of structure and function in all living organisms.
