Cell Walls: A Plant-Specific Feature

Definition and Function

The cell wall is a rigid structure located outside the cell membrane, providing protection and structural support to plant cells. Composed primarily of cellulose, it contributes to the strength and rigidity of the cell and the plant as a whole.

Absence in Animal Cells

In contrast to plant cells, animal cells lack cell walls. This absence allows animal cells to retain their flexibility and adaptability, facilitating cell movement, shape changes, and the formation of complex tissues.
