The centrosome is an organelle that is the principal place where cell microtubules are organized. Also, it controls the cell division cycle, the stages which lead up to one cell dividing in two.
The centrosome has seemingly only evolved in animal cells. Fungi and plants use different structures to organize their microtubules. Although the centrosome has a key role in effective mitosis in animal cells, it is not mandatory.A centrosome is formed of two centrioles at right angles to each another. They are enclosed by a shapeless mass of protein.The centrosome replicates during the interphase of the cell cycle.
