Definition: Centrioles are cylindrical structures that are composed of groupings of microtubules arranged in a 9 + 3 pattern. The pattern is so named because a ring of nine microtubule "triplets" are arranged at right angles to one another.

Centrioles are found in animal cells and help to organize the assembly of microtubules during cell division. Centrioles replicate during the interphase stage of mitosis and meiosis. Centrioles called basal bodies form cilia and flagella.
