The Cell Theory
- Every living organism is made up of one or more cells.
- The cell is the basic unit of structure and function.
- All cells arise from pre-existing cells.
The Cell Theory (additional)
- All cells contain hereditary information which is passed from cell to cell.
- All cells are basically the same in chemical composition.
- All energy flow of life occurs within cells.
Why is the cell theory called a theory and not a fact?
