So essentially our microtubules are made within our centrosome. Now, if the centrosome is responsible for a cell division that implies that the microtubules are also involved in cell division and that's exactly right. One function of our microtubule is to basically separate our chromosomes during cell division. So the microtubules are responsible for creating the metonic spindle that is formed during cell division. Now, another function of microtubule is to basically transport things within the cell so we can imagine the microtubules to be the highway system within our cell so we can move things from one location to a different location within the cell as a result of these network of highways our microtubules. Now, another important function of microtubules is the formation of specialized structures that help the cell move and these structures include our flagella as well as cilia.
