Microtubule play important roles in cell division, intracellular transport, cell movement and in the maintenance of cell structure. Microtubules(MTs) are polymers of dimeric alpha and beta tubulins. They are one of the cytoskeletal elements. They provide rigidity to the cell thereby maintaining its shape.
Beyond the role they play in internal cell movement, microtubules also work together to form larger structures that work on the outside of the cells. They can combine in very specific arrangements to form cilia and flagella. Cilia are little hairs you might see on the outside of a paramecium or other protists.
