However, they are not exactly necessary for mitosis to actually take place. Now, what exactly is the second function of the centriole? Well, basically, the centriole is our region that extends and creates those microtubules and microtubules compose our cytoskeleton. Now, the cytoskeleton is basically responsible for arranging and organizing the organelles found inside our cell. So we see that the placement of the centrils within the cell determines the position and location of the nucleus as well as the other organelles inside our body. And that's exactly why the centrosome that contains the centrioles is found right next to our nucleus.
