What is centrioles?
A centriole is an organelle that helps cells divide, or make copies of themselves.
Centrioles are only found in animal cells. All centrioles are made of protein strands called microtubules. Centrioles are made of nine triplets of microtubules arranged in a cylinder. Think of each microtubule like a plastic PVC pipe. The pipes are arranged with three put together in a triplet, then nine of those triplets are glued together to form an even bigger pipe. When two centrioles come together, they usually make a right angle.
