the cell wall is a network of fibers inside the cell that gives the cell its shape.
the cell wall is a barrier that allows certain substances into and out of the cell.
the cell wall is a series of folded membranes that produces and distributes proteins in the cell.

Explanation:

The cell wall is a rigid outer - layer in plant and some microbial cells. It provides structural support and protection. The network of fibers inside the cell that gives the cell its shape is the cytoskeleton. The barrier that allows certain substances in and out of the cell is the cell membrane. The series of folded membranes that produce and distribute proteins is the endoplasmic reticulum.
