What advantage is the cell wall in relationship to osmotic pressure

The advantage of cell wall in relationship to osmotic pressure is that the cell wall protects the cell from osmotic shock or osmotic lysis.

Explanation:

Osmosis is a process which takes place across the semipermeable membrane or the plasma membrane in the cell , the solvent on both the sides of the plasma membrane moves across the membrane to maintain the concentration of the solute.

This osmotic pressure can sometimes vary a lot, causing the cell to burst.  A cell wall maintains this and keeps the cell stable.
