Quizplus · Accepted Answer

The solid mass of cells that results from cleavage of the zygote is the morula. This occurs in the early stages of embryonic development and consists of a ball of about 16-32 cells. The trophoblast and blastocyst are formed after further cell division and differentiation, while gastrulation occurs later in embryonic development.
