The process that plant cells and animal cells undergo in cytokinesis are different.

Work Step by Step

Animal Cell: Contractile proteins (microfilaments) in the cell membrane cause the cell to pinch in the equator. This creates a cleavage furrow. The cell continues to pinch until it becomes two cells. Plant Cell: The Golgi body sends vesicles to the equator, which merge into tubular structures that become the cell membrane. Cell plates develop from vesicles. The vesicles also secrete substances like pectin. Both cells then secrete cellulose to create the cell wall.
