WebA single cell embryo is called a 2PN zygote (for 2 pronuclei). The 2PN zygote divides into an embryo (2-4 cells), the "morula" approx. 16 - 32 cells) and finally a "blastocyst" embryo. The embryo spontaneously "hatches" from its shell (zona pellucida) at the blastocyst stage of development and is ready to attach to the uterine wall.
