Final answer:
Cytokinesis begins during late anaphase and is completed just before the next interphase. In animal cells, a contractile ring is formed to separate the cytoplasm into two daughter cells, while in plant cells, a cell plate forms to divide the cytoplasm.
Step-by-step explanation:
Cytokinesis begins during late anaphase and is completed just before the next interphase. In animal cells, a contractile ring composed of actin filaments forms just inside the plasma membrane, constricting and eventually pinching off the cytoplasm to form two daughter cells. This process is different in plant cells, where a cell plate forms between the two new nuclei, which eventually develops into a cell wall.
