The Cell TheoryThe Cell Theory
1.1. All living things are All living things are composed of cellscomposed of cells
2.2. Cells are the basic Cells are the basic units of structure and units of structure and function in living function in living thingsthings
3.3. New cells are New cells are produced from produced from existing cellsexisting cells
