The cell wall is a rigid layer that surrounds the cell membrane of a plant cell. It’s made mainly of the complex carbohydrate called cellulose. The cell wall supports and protects the cell. The cell wall isn’t solid like a brick wall. It has tiny holes in it called pores. The pores let water, nutrients, and other substances move into and out of the cell.
