Correct Answer: Cell wall

Solution : The correct option is the Cell wall .

Plant cells have an additional layer around the cell membrane called the "cell wall." The cell wall is a rigid outer layer that provides structural support and protection to the plant cell. It consists mainly of cellulose, a complex carbohydrate that gives the cell wall its strength and rigidity. Animal cells do not have a cell wall; instead, they typically have a flexible cell membrane that surrounds the cell.
