The Early Cell Divisions of Human Development Differ from Other

Question

The early cell divisions of human development differ from other mitotic cell divisions in that:
A)cells do not replicate all chromosomes prior to dividing; this helps the cells differentiate.
B)cells do not grow in size; they subdivide the cytoplasm of the fertilized egg.
C)cells move as they divide.
D)they are unequal; some daughter cells are much larger than others.
E)All of these choices are correct.

Accepted Answer

The early cell divisions of human development differ from other mitotic cell divisions in that cells do not grow in size; they subdivide the cytoplasm of the fertilized egg. This is known as cleavage and leads to the formation of smaller daughter cells called blastomeres. These blastomeres eventually differentiate and specialize to form the different organs and tissues of the human body.
