Final answer:
The cytoskeleton has multiple functions including maintaining cell shape, enabling cell movement, aiding in cell division, and facilitating cell communication.
Step-by-step explanation:
The cytoskeleton is a group of fibrous proteins that provide structural support for cells and has several functions. It helps to maintain cell shape, allows movement of certain cells, such as muscle cells, through contraction of actin fibers, and is involved in some cell-to-cell or cell-to-matrix interactions. The cytoskeleton also plays a role in cell division by pulling replicated chromosomes to opposite ends of a dividing cell. Additionally, it is involved in intracellular movement of substances and holds organelles in place.
