* Plasma membrane: This is the outermost boundary of all cells, including both animal and plant cells. It acts as a barrier between the cell's internal environment (cytoplasm) and the external environment.
Here's a breakdown:
* Animal Cells: The plasma membrane is the only membrane that surrounds the cell.
* Plant Cells: Plant cells have a cell wall outside of the plasma membrane. The cell wall provides structural support and protection.
Therefore, both animal and plant cells have a plasma membrane, although plant cells have an additional cell wall.
