Answer: Microtubules are the components of the cytoskeleton. Functions: - form a framework for structures such as the spindle apparatus that appears during cell division hence aid in the separation of chromosomes during mitosis. -also components of cilia and flagella. -determine cell shape and in a variety of cell movements Microtubules are polar structures with two distinct ends: a fast-growing plus end and a slow-growing minus end. Polarity helps in determining the direction of movement along microtubules, Solution Answer: Microtubules are the components of the cytoskeleton.
