2. OVUM (EGG CELL)

The ovum is the female gamete that develops within the female Ovary. It is spherical in shape, non-motile, and measures 130-140 µm in diameter. The ovum consists of a Nucleus, Cytoplasm, and surrounding membranes. The Nucleus contains a haploid set of Chromosomes: 22 autosomes and 1 sex X chromosome.

The process of female germ Cell development is known as oogenesis. Oogenesis comprises three distinct periods: proliferation, growth, and maturation. The proliferation period takes place during embryonic development, whereas the maturation period is completed following ovulation.
