Here's why:

* Structure: The cell wall is located outside the cell membrane and provides structural support and protection for the cell.

* Composition: It's primarily made of cellulose, a complex carbohydrate that forms strong fibers.

* Function: The cell wall helps maintain the plant's shape, prevents bursting due to internal pressure, and provides a barrier against pathogens.

Think of the cell wall as the plant's "skeleton" - it gives the cell its shape and strength.
