WebApr 11, 2024 · A cleavage furrow is a structure that occurs in the middle of the animal cell that undergoes cytokinesis. Usually, it forms after the anaphase of cell division. Also, the main function of the cleavage furrow is to separate the dividing cell into two daughter cells. Actually, cytokinesis is the division of the cytoplasm completely separating…
WebThe cleavage site, located in the center of the cell, is called the cleavage furrow. Vesicles derived from the Golgi apparatus migrate to the middle of the cell and help in the cleavage by forming a contractile ring composed of actin filaments.
