Answer

Cytokinesis in animal cells involves a cleavage furrow, while in plant cells, it involves forming a cell plate. Explanation 1. Define Cytokinesis in Animal Cells In animal cells, cytokinesis occurs through a process called cleavage. A contractile ring composed of actin and myosin filaments forms at the cell's equator, constricting the cell membrane to create a cleavage furrow that eventually divides the cell into two daughter cells. 2. Define Cytokinesis in Plant Cells In plant cells, cytokinesis occurs by forming a cell plate. Vesicles from the Golgi apparatus coalesce at the center of the cell, forming a cell plate that grows outward until it fuses with the cell membrane, dividing the cell into two.
