Q. Statement I: In the fetal ovary, oogonia start division, enter into prophase-I of the meiotic division and get temporarily arrested at that stage, are called primary follicles.

Solution:

• Oogenesis is initiated during the embryonic develop ment stage when a couple of million gamete mother cells (oogonia) are formed within each fetal ovary (about third month of foetal ovary), no more oogonia are formed and added after birth.
• These cells start division and enter into prophase-I of the meiotic division and get temporarily arrested at that stage, called primary oocytes.
• Each primary oocyte then gets surrounded by a layer of granulosa cells and then called the primary follicle.
