Quick look: Found only in animal cells and some lower plants, a centriole is composed of short lengths of microtubules lying parallel to one another and arranged around a central cavity to form a cylinder. centriole is composed of short lengths of microtubules arranged in the form of an open-ended cylinder about 500nm long and 200nm in diameter.
Centrioles are made of nine bundles of microtubules, that are arranged in a ring. The centrioles play a major role in cell division. In animal cells the centrioles play a major role in cell division but the plant cells have the ability to reproduce even without the centrioles.hey are found in most of the eukaryotic cells. The centrioles are made of groups of microtubules,these microtubules are arranged in a pattern of 9+3. The pattern of the microtubules for a ring of 9 microtubules known as triplets and the microtubules are arranged at right angles to one another.
