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:
Cell division is a process by which a cell divides and it is necessary for the growth and development of cells. All cells undergo two types of division which is either Meiosis or Mitosis.
Mitosis is the equational division that forms 2 daughter cells having the same number of chromosomes as their parental cell.
Meiosis is the reductional division that forms 4 daughter cells having half number of chromosomes as their parental cells.
