Treatment. Definition :. Cleavage is a process of rapid and synchronous mitotic cell divisions of the zygote to form numerous cells for building up the offspring’s body . Cleavage differs from other forms of cell division in that it increases the number of cells without increasing the mass.. gastrulation:reading.
