Cytokinesis begins during telophase. The cell divides into two daughter cells.In animal cells a cleavage furrow forms around the middle of the cell. The cell membrane is pulled inwards by the cytoskeleton until it meets in the middle and fuses to form two cells.In plant cells vesicles from the Golgi apparatus begin to assemble in the same plane as where the metaphase plate was.The vesicles fuse with each other and the cell membrane. The cell is therefore divided into two.Sections of cell wall are synthesised along the dividing wall.
