Cell Theory
By: Caleb Kindel and Tanner McCarroll
Cell theory definition
A basic modern biology first started by Matthis Scheiden and Theodor Schwann in 1838-39, that cells are the basic units of structure and function in living organisms.
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).
different cells
Plant cell
Has a cell structure of a cube and has no nucleus.
Animal cell
Has a cell structure of a sphere and has a nucleus.
Bactirial cell
Has a cell structure of a cylinder, with a tail to help move around and it has no nucleus.
3 parts of the cell theory
1. All known living things are made up of one or more cells.
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.
