Question

Write notes on the organisation of a centriole

Answer 1

In cell biology a centriole is a cylindrical cell structure composed mainly of a protein called tubulin that is found in mosteukaryotic cells. Centrioles are absent from Pinophyta, flowering plants and most fungi and are only present in the male gametes of charophytes, bryophytes, seedless vascular plants, Cycads, and Gingko. An associated pair of centrioles, surrounded by an amorphous mass of dense material, called the pericentriolar material, or PCM, makes up a compound structure called a centrosome.
