Centrioles are cylindrical structures that are composed of groupings of microtubules arranged in a ring of nine triplets. They are found in animal cells and help to organize the assembly of microtubules during cell division. Credit: Stocktrek Images/Getty Images.
And what are centrioles made of? Microtubules. Centriole Structure A centriole is a small set of microtubules arranged in a specific way. There are nine groups of microtubules. When two centrioles are found next to each other, they are usually at right angles. The centrioles are found in pairs and move towards the poles (opposite ends) of the nucleus when it is time for cell division. During division, you may also see groups of threads attached to the centrioles. Those threads are called the mitotic spindle. Relaxing When There's no Work We already mentioned that you would find centrioles near the nucleus. You will not see well-defined centrioles when the cell is not dividing. You will see a condensed and darker area of the cytoplasm called the centrosome. When the time comes for cell division, the centrioles will appear and move to opposite ends of the nucleus.
