CELL THEORY
The cell theory is one of the foundations of modern biology.
This generally accepted theory includes the following ideas:
Cells are the smallest living things.
All organisms consist of one or more cells.
Metabolism occurs within cells.
Hereditary traits are transferred via cells.
All cells are created through the division of existing cells. (In other words, no cells are spontaneously generated.)
