This fissure or âcrackâ is called the cleavage furrow. The furrow deepens as the actin ring contracts; eventually the membrane is cleaved in two. Cytokinesis: During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate.
Cytokinesis in Plant Cells. Plant cells have walls, so cytokinesis cannot proceed with a cleavage furrow. Instead, during telophase a cell plate forms across the cell in the location of the old metaphase plate. 1  During telophase, membrane-enclosed vesicles derived from the Golgi apparatus migrate to the center of the cell where the metaphase plate used to be and fuse to form a cell plate.
