Cytokinesis is the final stage in the cell cycle. The cytoplasm of the dividing cell is separated in two. The way this happens is different for animal and plant cells.

In animal cells, the cell forms a contractile ring in the middle of the dividing cell. As the ring contracts, it creates a cleavage furrow, which eventually pinches the cell in two.

In plant cells, vesicles migrate to the middle of the cell and fuse to form a cell plate (which eventually becomes the plasma membrane). A cell wall then develops between the two cells.

Once cytokinesis is complete, cells once again return to interphase.
