Mitosis, a form of cell division, enables organisms to grow and reproduce. Dividing cells go through an ordered series of events called the cell cycle.

In metaphase, the nuclear membrane disappears completely. The spindle fully develops and the chromosomes align at the metaphase plate (a plane that is equally distant from the two poles).

Chromosomes are held at the metaphase plate by the equal forces of the polar fibers pushing on the centromeres of the chromosomes.

In animal cells, two pair of centrioles align at opposite poles of the cell.
