Here's why:
* The cytoskeleton is a network of protein filaments: These filaments are like internal scaffolding that helps the cell maintain its shape, organize its internal components, and move.
* It interacts with the cell membrane: The cytoskeleton's filaments attach to the membrane, providing structural support and helping to maintain its integrity.
* It's involved in cell movement: The cytoskeleton plays a role in how cells move, change shape, and transport substances within the cell.
While the cell wall provides support in plant cells, it's not a direct component of the cell membrane. The cytoskeleton is the primary organelle that provides strength and support for the membrane in both plant and animal cells.
