by a network of several kinds of protein fibers that supports the shape of the cell and anchors its organelles. This mesh like network is called the cytoskelton. Within the cytoskeleton, hollow protein fibers called microtubules aid in moving chromosomes during cell division y forming cylindrical organelles called centrioles. Protruding from the surfaces of many eukaryotic cells are long threadlike organelles called flagella, which are used in locomotion. Flagella are actually complex cables of microubules.
