WebIn animals, cell division occurs when a band of cytoskeletal fibers called the contractile ring contracts inward and pinches the cell in two, a process called contractile cytokinesis. The indentation produced as the ring contracts inward is called the cleavage furrow. Animal cells can be pinched in two because they’re relatively soft and squishy. WebMar 1, 2024 · 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. In essence, cytokinesis is the partitioning of the cytoplasm into two equal parts, each of which contain a diploid chromosomal set identical to that of the parent cell.
