Best Answer

Centrioles are cylindrical structures, found in animal cells, that are composed of groupings of microtubules arranged in a 9 + 3 pattern. They help to organize the assembly of microtubules during cell division.

A centriole is a barrel-shaped organelle[1] found in most animal eukaryotic cells, though absent in higher plants and most fungi.[2] The walls of each centriole are usually composed of nine triplets of microtubules (protein of the cytoskeleton). Deviations from this structure include Drosophila melanogaster embryos, with nine doublets, and Caenorhabditis elegans sperm cells and early embryos, with nine singlets.[3][4] An associated pair of centrioles, arranged perpendicularly and surrounded by an amorphous mass of dense material (known as the pericentriolar material) constitutes the compound structure known as the centrosome.[1]
