Cytokinesis. Cytokinesis is the process in which the cell actually divides into two. With the two nuclei already at opposite poles of the cell, the cell cytoplasm separates, and the cell pinches in the middle, ultimately leading to cleavage.
Cytokinesis begins in anaphase in animal cells and prophase in plant cells, and terminates in telophase in both, to form the two daughter cells produced by mitosis.
During cytokinesis, the cytoplasm splits in two and the cell divides. Cytokinesis occurs somewhat differently in plant and animal cells, as shown in Figure below. In plant cells, a cell plate forms along the equator of the parent cell. Then, a new plasma membrane and cell wall form along each side of the cell plate.
The cells that have been undergoing cell division through mitosis are now separated, and each cell is an individual cell with a complete set of DNA; however, cytokinesis is different between plant cells and animal cells. The reason for this is that plant cells have a cell wall in addition to their cell membrane.
Likewise, what is responsible for cytokinesis in plant cells? During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. In plant cells, a new cell wall must form between the daughter cells.
