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:

- Need help with three question. Multiple choise. 1.) How is the outcome of meiosis different from the outcome of mitosis? a.) The daughter cells produced in mitosis are genetically different from the parent cells, but have the same number of chromosomes, while these are genetically similar in case of meiosis and have fewer chromosomes. b.) The daughter cells produced in mitosis are genetically similar to the parent cells and have the same number of chromosomes, while these are genetically different in meiosis and have half the number of chromosomes. c.) The daughter cells produced in both cases are genetically similar to the parent cells, but in meiosis, there are fewer chromosomes. d.) The daughter cells produced in both cases are genetically different, but in mitosis, there are fewwer chromosomes in daughter cells. 2.)
