MAKE CONNECTIONS As you learned in Chapter 12,mitosis gives rise to two daughter cells that are genetically identical to the parent cell. Yet you, the product ofmany mitotic divisions, are not composed of identical,zygote-like cells. Why?
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
