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

Cell division is the process by which new cells are produced during embryonic development. Differentiation refers to the specialization of cells into different types. Preformation is the theory that a miniature version of an organism is preformed in either the egg or sperm. Morphogenesis refers to the process by which an organism takes shape and its organs and tissues grow and differentiate. Epigenesis refers to the idea that an organism develops through a series of stages from a relatively undifferentiated egg cell.
