Correct Answer: Cell wall

Solution : The correct option is the Cell wall.

The cell wall is the outer covering of a plant cell, present over the cell membrane. It is absent in animal cells. Instead, an animal cell has only a plasma membrane as its outer covering. The cell wall is a rigid structure. It is composed of cellulose, pectin, and hemicellulose. It protects the cell and also provides structural support. It also filters molecules that move in and out of the cell.
