The centrosme, in the animal cell, is also called the "microtubules organizing center." The centrosome is the area in the cell where microtubules are produced. In the centrosome there is a pair of small organelles, the centrioles, each made up of a ring of nine groups of microtubules. The centrosome begins to duplicate when a pair of even smaller bodies inside the centroso...
