What is the role of the cytoskeleton?

The role of the cytoskeleton is primarily to provide structural support and shape to the cell. It is composed of a network of protein fibers, including microtubules, microfilaments, and intermediate filaments, which work together to maintain the cell's integrity and shape. The cytoskeleton also plays critical roles in cellular motility, the organization of organelles, and the transport of materials within the cell.

In essence, by providing a scaffold-like structure, the cytoskeleton helps the cell withstand various physical stresses and maintain its shape, which is essential for its overall functionality and interaction with the environment. This structural function is fundamental to various processes, including cell division and movement, ensuring that the cell can effectively carry out its biological functions.
