During mitosis, the centrioles play a crucial role in organizing the microtubules that form the spindle fibers. The spindle fibers are responsible for separating the chromosomes during cell division. The centrioles replicate and migrate to opposite ends of the cell, and they help to arrange the spindle fibers that attach to the chromosomes. The spindle fibers pull the chromosomes to opposite ends of the cell, allowing cytokinesis to occur.

It is important to note that the role of centrioles during mitosis is still a topic of debate among scientists. Some researchers believe that centrioles are active players in regulating mitosis, while others believe that they are simply passengers. More research is needed to fully understand the precise regulation of mitosis by centrioles.
