Final answer:
In animal cells, cytokinesis occurs through cleavage furrow formation, while in plant cells, it involves the formation of a cell plate.
Step-by-step explanation:
In animal cells, cytokinesis occurs through the process of cleavage furrow formation. The plasma membrane of the parent cell pinches inward along the cell's equator until two daughter cells form. On the other hand, in plant cells, cytokinesis involves the formation of a cell plate along the equator of the parent cell. This cell plate eventually develops into a new cell wall that separates the two daughter cells.
