The cleavage begins as a small … WebAfter the cleavage has produced over 100 cells, the embryo is called a blastula. The blastula is usually a spherical layer of cells (the blastoderm) surrounding a fluid-filled or yolk-filled cavity (the blastocoel). During cleavage, the zygote rapidly divides into multiple cells without increasing in size. Mammals at this stage form a structure ...
