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:
The cell actually stays in interphase mostly. When it is prepared for growth & chromosomal replication, it involves four different stages to complete the process. Gap1 or Growth phase where all parameters are checked which is suitable for cell division. S phase refers to synthesis. Gap2 phase ensures the chromosomal replication and Mphase is the mitosis phase.
