CMMB 403Fertilization - correct answer Fusion of an egg and sperm cell to produce a zygote Cleavage - correct answer rapid mitotic cell division of the zygote that begins immediately after fertilization Gastrulation - correct answer In animal development, a series of cell and tissue movements in which the blastula-stage embryo folds inward, producing a three-layered embryo, the gastrula. Organogenesis - correct answer process of organ formation that takes place during the first two ...
