Question

The cell produced by fertilization of the ovum by sperm is called a
A)gamete
B)secondary oocyte
C)cleavage
D)zygote
E)morula

Accepted Answer

The cell produced by fertilization of the ovum by sperm is called a zygote. It is the first cell of a new individual and contains genetic information from both the mother and father. It will undergo multiple cell divisions to form the embryo. Gametes are the reproductive cells (sperm and egg) that unite during fertilization. Secondary oocyte is an immature egg cell that has not yet been fertilized. Cleavage refers to the rapid cell divisions that occur in the zygote after fertilization. Morula is a stage in embryonic development where the cells have formed a solid ball of cells.
