WebCytokinesis is one of the most dramatic changes in cell shape and requires an extensive reorganization of the cell’s cytoskeleton. Here, we describe the cytoskeletal structures, … WebIn animals, cytokinesis is centripetal. In animal cells, cytokinesis is accomplished by furrow formation which starts from the cell membrane. In this process cleavage of cytoplasm takes place. Thus, in animal cells, cytokinesis starts from the periphery and moves towards the centre, i.e., centripetal. So, the correct answer is ' Centripetal'.

WebIn cells such as animal cells that lack cell walls, cytokinesis begins following the onset of anaphase. A contractile ring composed of actin filaments forms just inside the plasma membrane at the former … 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. WebCytokinesis is the final step of cell division that leads to the physi - cal separation of the two daughter cells.1-3 Cytokinesis normally proceeds through sequential steps of cleavage plane specification between the segregated chromosomes, formation and constric-tion of an actomyosin-based contractile ring, stabilization of the philosophy of cbt
