WebNational Center for Biotechnology Information WebDefinition of Cytokinesis. The term cytokinesis merely refers to the cell motion or cell division. It is defined as a form of cytoplasmic division, which occurs after the chromosomal separation.In plants, the cytokinesis usually begins from the prophase stage of the cell cycle and lasts to the telophase stage. Oppositely, cytokinesis in the animal cells begins …
WebCytokinesis in an animal cell: an actin ring around the middle of the cell pinches inward, creating an indentation called the cleavage furrow. Cytokinesis in a plant cell: the cell plate forms down the middle of the … In cell biology, the cleavage furrow is the indentation of the cell's surface that begins the progression of cleavage, by which animal and some algal cells undergo cytokinesis, the final splitting of the membrane, in the process of cell division. The same proteins responsible for muscle contraction, actin and myosin, begin the process of forming the cleavage furrow, creating an actomyosin ring. …
