Noun. 1. centriole-one of a pair of small cylindrical cell organelles near the nucleus in animal cells; composed of nine triplet microtubules and form the asters during mitosis. cell organ, cell organelle, organelle-a specialized part of a cell; analogous to an organ; the first organelle to be identified was the nucleus.entriole. 1. Either of two organelles near the nucleus involved in cell division. 2. One of a group of tiny tubules near the nucleus of a cell. Centrioles play a part in cell division.
1 Centrioles occur as paired cylindrical organelles together with pericentriolar material (PCM) in the centrosome of an animal cell. 2  Centrioles are found as single structures in cilia and flagella in animal cells and some lower plant cells. 3  Centrioles are constructed of microtubules.entrioles are absent from the cells of higher plants. When animal cells undergo mitosis they are considered by some to benefit from the presence of centrioles which appear to control spindle fibre formation and which later has an effect on chromosome separation.
