In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. Centrioles are found in most eukaryotic cells, but are not present in conifers (Pinophyta), flowering plants (angiosperms) and most fungi, and are only present in the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and Ginkgo. A bound pair of centrioles, surrounded by a highly … WebCentrosome or cell centre is the area of cytoplasm (often a clear zone) around the centriole. It is also called micro-centrum. Centrosome is found lying in the centre of the cell, near the nucleus, in the cytoplasm. In Metazoa, centrosome lies outside nucleus, but in Protozoa it lies within the nucleus.
