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 occur as paired cylindrical organelles together with pericentriolar material (PCM) in the centrosome of an animal cell. 1  Centrioles are found as single structures in cilia and flagella in animal cells and some lower plant cells. 2  Centrioles are constructed of microtubules.
