cell wall
Rigid plant boundary
A cell wall is the rigid outer layer surrounding certain cells, providing structural support and protection.
Plant cells have cell walls made of cellulose; bacterial and fungal cells have walls of different composition.
Animal cells lack cell walls entirely, having only flexible membranes.
The cell wall gives plants their rigidity.
