Question

Once cleavage starts, the zygote starts dividing, forming cells called ________.
A) morulas
B) blastomeres
C) blastocytes
D) differentiated
E) blastocysts

Accepted Answer

The cells formed after cleavage are called blastomeres. Morulas are a stage of development after the zygote but before the blastocyst stage. Blastocytes and blastocysts are later developmental stages after the formation of a blastula, which forms from blastomeres. "Differentiated" cells refer to cells that have matured and taken on specialized functions, which has not yet occurred in the early stages of embryonic development.
