The Stages of Mitosis and Cell Division
By Regina Bailey

Cytokinesis is the division of the cytoplasm in eukaryotic cells that produces distinct daughter cells. Cytokinesis occurs at the end of the cell cycle following mitosis or meiosis.

In animal cell division, cytokinesis occurs when a contractile ring of microfilaments forms a cleavage furrow that pinches the cell membrane in half. In plant cells, a cell plate is constructed that divides the cell in two.
