This fissure or âcrackâ is called the cleavage furrow. The furrow deepens as the actin ring contracts; eventually the membrane is cleaved in two. Cytokinesis: During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate.
Cleavage. Cleavage is a series of rapid cell divisions without cell growth or gene expression which occurs in early embryogenesis. Early cleavage divisions in most embryos are reductive. During cleavage, the cytoplasm is divided into smaller and smaller cells, called blastomeres.The total cellular volume of the embryo stays the same, but the number of cells within the embryo increases. Cleaving cells have a modified cell cycle, in which the two gap phases, G1 and G2, are completely omitted.leavage.
