​These are the original parts of the Cell Theory, but in modern times other features have been added over time.

The generally accepted parts of modern cell theory include:

1. All known living things are made up of one or more cells.

2. All living cells arise from pre-existing cells by division.

3. The cell is the fundamental unit of structure and function in all living organisms.

4. The activity of an organism depends on the total activity of independent cells.

5. Energy flow (metabolism and biochemistry) occurs within cells.

6. Cells contain DNA which is in the chromosomes and RNA found in the cell nucleus and cytoplasm.

7. All cells are basically the same in chemical composition in organisms of similar species.
