Here's why:

* Shape and Protection: The cell wall is a rigid structure that surrounds plant cells, fungi, bacteria, and some protists. It provides structural support, giving the cell its shape and protecting it from bursting.

* Not Found in Animal Cells: Animal cells lack a cell wall, which allows them to be more flexible and move around freely. They rely on internal structures like the cytoskeleton for support.
