Centrosomes are present in animal cell. In cell biology, the centrosome (Latin centrum 'centre' + Greek sōma 'body') (archaically cytocentre [1]) is an organelle that serves as the main microtubule organizing centre (MTOC) of the animal cell, as well as a regulator of cell-cycle progression. Owing to their capacity to grow MT filaments, they orchestrate various fundamental cellular processes, such as cell division, vesicle trafficking, cell polarization, motility, and ciliogenesis.
