What is the primary role of the cytoskeleton?

To digest nutrients

To maintain cell shape and assist in movement

The primary role of the cytoskeleton is to maintain cell shape and assist in movement. The cytoskeleton is a complex network of fibers and filaments found within cells, providing structural support and helping to organize cellular components. Its components, such as microtubules, microfilaments, and intermediate filaments, play critical roles in maintaining the cell's shape, offering resistance to deformation, and facilitating movement through processes like cell division, intracellular transport, and the movement of cilia and flagella in certain types of cells. By being integral to cellular architecture and mobility, the cytoskeleton ensures that the cell can maintain its structure and adapt to various functions necessary for survival.
