Cytokinesis (image)
The fina+E281l step of cell division when the cytoplasm divides
Cytokinesis is the process by which the cytoplasm of a single eukaryotic cell divides into two daughter cells. The process usually begins during telophase, the final stage of mitosis, and proceeds through completion in different ways in different organisms.
The attached image shows a dividing cell (possibly an animal cell) in the process of cytokinesis. The cell has completed the process of mitosis, and now the cytoplasm is being divided equally between the two daughter cells. This division is facilitated by a contractile ring of actin and myosin filaments, called the cleavage furrow, which forms around the cell. As the ring tightens, it creates a deepening indentation in the cell membrane. Finally, the ring meets at the center of the cell, and the cell membrane fuses to form two separate daughter cells.
It is important to note that the image only represents one possible way cytokinesis can occur. In some organisms like plants, cytokinesis is facilitated by the formation of a cell plate rather than a cleavage furrow, resulting in the formation of a cell wall between the two daughter cells.
