Centriole

A cellular organelle, found close to the nucleus in many eukaryotic cells, consisting of a small cylinder with microtubular walls, 300-500 nm long and 150-250 nm in diameter. It contains nine short, parallel, peripheral microtubular fibrils, each fib

The centriole is a cytoplasmic structure in most eukaryote cells. It is involved in cell division and in the formation of cilia and flagella. Centrioles are not found in vascular plants and in most fungi.[1]

Most centrioles are nine sets of microtubule triplets, arranged in a cylinder. A pair of centrioles, arranged perpendicularly and surrounded by a mass of dense material makes up the centrosome.[2]
