Explanation:
Detailed explanation-1: -Hydrostatic pressure of the fluid creates a large cavity in the morula called a blastocoel. Embryoblast cells also known as the inner cell mass form a compact mass of cells at the embryonic pole on one side of the cavity that will go on to produce the embryo proper. The embryo is now termed a blastocyst .
Detailed explanation-2: -Morulae, referred to as day 4 embryos, are characterized by cell compaction beginning at the 8-to 10-cell stages in early embryonic development, and are described as “an indistinguishable mass of cells” [10].
