Colour-enhanced Transmission Electron Micrograph (TEM) showing a pair of centrioles. One centriole in transverse section (above),the other in longitudinal section; each centriole has a cylindrical system of 9 triplet microtubules (as do the basal bodies of all eukaryotic cilia and flagella); centrioles typically lie perpendicular to one another; in animal cells,the centrioles act as microtubule organizing centres and control spindle construction from microtubules during cell division.
