Answer by  jsmith (2067)

Centrioles are organelles in animal cells that are short tube-like structures made out of microtubules. They provide a place for the mitotic spindle to anchor when the cells are dividing by mitosis.

It is a hollow cylindrical organelle found in most algae, animal, and fungi cells, but not commonly in plants. The walls of each centriole contain nine triplets of microtubules, with each fixed at a right angle. When looking down the tube, one end of the triplet pair points just outwards and the other end points are just inwards.

Centrioles are involved in mitosis (cell division) of eukaryotic cells. Each cell has two centrioles, responsible for correctly lining up and separating chromosomes during the metaphase stage of mitosis.
