Blastulation. 1 - morula, 2 - blastula.
Morula is a stage of embryonic development in animals, including the 16-cell phase, the 32-cell phase, and the 64-cell phase. The morula is produced by embryonic cleavage, the rapid cell division of the zygote with virtually no growth. The morula is a solid ball; after the 64-cell phase, it develops into a hollow ball, the blastula.
