About morula.
Introduction:
Morula is an early phase of development after fertilization if cells are quickly divided in a mitotic manner to create a solid cell mass that is 12-15 cells with a "mulberry" characteristic.
Explanation of Solution
Morula is a dense globular mass of the blastocyst 16 32 blastomeres produced by the zygote cleavage. The blastocyst stage starts with the existence of the cavity which is called blastocoele. The human embryo enters the uterus between 3 to 4 days of development.
Thus, following this stage, a cavity is formed at this point of cell mass of the blastocyst.
