Answer:
Is found in all cells
Step-by-step explanation:
- The cell membrane is not made up of chromatin. Chromatin is found in DNA.
- The cell membrane obviously does not produce energy for the cell. It acts as a barrier that lets things in and keeps things out.
- Lastly, the cell membrane is not a rigid layer of cellulose. Cellulose is a component of a cell wall.
To conclude, the cell membrane is found in all cells.
