- all cells come from preexisting cells
The MODERN version of the cell theory (7)
- all living things are made up of one or more cells
- all living cells arise from pre-existing cells by division
- the cell is a fundamental unit of structure and function in all living organisms
- the activity of an organism depends on the total activity of independent cells
- energy flow occurs within cells (metabolism and biochemistry)
- cells contain hereditary information (DNA) which is passed from cell to cell during cell division
- all cells are basically the same in chemical composition in organisms of similar species
