A major role of the cell wall is to form a framework for the cell to prevent over expansion. Cellulose fibers, structural proteins, and other polysaccharides help to maintain the shape and form of the cell. Additional functions of the cell wall include:

Support: The cell wall provides mechanical strength and support. It also controls the direction of cell growth.

Withstand turgor pressure: Turgor pressure is the force exerted against the cell wall as the contents of the cell push the plasma membrane against the cell wall. This pressure helps a plant to remain rigid and erect, but can also cause a cell to rupture.

Regulate growth: The cell wall sends signals for the cell to enter the cell cycle in order to divide and grow.

Regulate diffusion: The cell wall is porous allowing some substances, including proteins, to pass into the cell while keeping other substances out.

Communication: Cells communicate with one another via plasmodesmata (pores or channels between plant cell walls that allow molecules and communication signals to pass between individual plant cells).

Protection: The cell wall provides a barrier to protect against plant viruses and other pathogens. It also helps to prevent water loss.

The cell wall is the wall located immediately outside of the cell membrane.  

Explanation:

  • It protects cells from getting expanded due to the external stimuli.
  • It provides mechanical strength and support.
  • Prevents the leakage of cytoplasmic materials.
  • Protects and filters the unwanted molecules entry and exit of the cell.
  • It is flexible but helps to maintain a proper shape of the cell.
  • The animal cells which are eukaryotic in nature do not have cell wall, it is covered just by a membrane called plasma membrane.
