What is the function of microtubules in a cell?

Microtubules are conveyer belts inside the cells. They move vesicles, granules, organelles like mitochondria, and chromosomes via special attachment proteins. They also serve a cytoskeletal role. Structurally, they are linear polymers of tubulin which is a globular protein.

Similarly one may ask, what is the purpose of microtubules in a cell?

Other than support, organelle movement, and cell division, microtubules also play a part in forming large structures on the outside of the cells. Microtubules can combine in very specific bundles to form cilia and flagella for cell movement.

What is the structure and function of microtubules?

Microtubules are the largest cytoskeletal filaments in cells, with a diameter of 25 nanometers. They are made out of subunits called tubulin. Each tubulin subunit is made up of one alpha and one beta tubulin that are attached to each other, so technically tubulin is a heterodimer, not a monomer.
