B. Cell membranes
Cell membranes are found in all cells, providing a barrier that separates the interior of the cell from the external environment. The other options do not exist in all cells:
- A. Flagella: Not all cells have flagella; they are found in some types of cells, particularly certain bacteria and sperm cells.
- C. Cell wall: Only certain types of cells, like those of plants, fungi, and some bacteria, have cell walls.
- D. Chloroplasts: These are found only in plant cells and some algae, not in all cells.
