Centrosomes

In animal cells, centrosomes migrate to opposite poles of the cell during prophase of cell division.

Scientists are unsure why centrosomes are found in animal cells, since plant cells can divide properly without them.

Centrosomes act as the microtubule organising centre, where astral, kinetochore, and non-kinetochore microtubules extend from.

The centrosome introduced by the spermatozoon has divided into two centrosomes, one at each pole of the nucleus.
