Question

Which structure will actually become the fetus?
a.) Morula b.) Blastocyst
c.) Inner cell mass d.) zygote

Answer 1

Explanation:

The trophoblast does not contribute to the formation of the embryo proper; the embryo develops from the inner cell mass. Fluid collects between the trophoblast and the greater part of the inner cell mass, and thus the morula, is converted into the blastodermic vesicle (also called the blastocyst or blastula).

hence option (B) is correct.
