   What is a cell wall in a plant cell?

   • The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell. Cell walls are found in both prokaryotes and eukaryotes, although not all cells have cell walls. In Figure 5.13.1 5.13. 1, the diagram of a plant cell, you see a structure external to the plasma membrane which is the cell wall.
