How do the components of the cytoskeleton (microtubules, microfilaments, and intermediate filaments) maintain cell shape and facilitate motility?

Verified Answer

The cytoskeleton is a network of protein filaments that provides structural support and facilitates cell movement. Microtubules are hollow cylinders that resist compression, maintain cell shape, and serve as tracks for organelle movement and chromosome segregation during cell division. Microfilaments (actin filaments) are solid rods that bear tension, contribute to cell shape, muscle contraction, and amoeboid movement. Intermediate filaments are rope-like proteins that provide mechanical strength and anchor organelles, giving the cell durability and helping maintain its shape. Together, these components create a dynamic framework for both structural integrity and various forms of cellular motility.
