As an Embryo Develops,new Cells are Produced as the Result

Question

As an embryo develops,new cells are produced as the result of
A)differentiation.
B)preformation.
C)cell division.
D)morphogenesis.
E)epigenesis.

Accepted Answer

As an embryo develops, new cells are produced through cell division, specifically through the process of mitosis. The other choices refer to different aspects of embryonic development, but do not directly relate to the production of new cells. Differentiation is the process whereby cells become specialized for specific functions, while preformation refers to older models of embryonic development that proposed that embryos were preformed and simply grew larger over time. Morphogenesis refers to the process of shaping the organism's final form, while epigenesis refers to the notion that development progresses through the interaction of genes and environment.
