Here's why this is important:

* Structure and Support: The cell wall provides rigidity and shape to the cell, helping to maintain its structure and prevent bursting due to changes in internal pressure.

* Protection: It acts as a barrier, protecting the cell from damage and infection.

* Regulation: The cell wall plays a role in regulating the passage of substances into and out of the cell.

While animal cells lack a cell wall, plants and algae rely on this structure for their unique functions and survival.
