Question

Why does spermatogenesis result in four spermatids but oogenesis only in one ovum?

Answer 1

Spermatogenesis:

1. Spermatogenesis, a process of cell development, produces fertilizing sperm that eventually combine with an egg to form a zygote.
2. Sertoli cells are essential for normal spermatogenesis because they protect cell connections and give male germ cells the nutrients they need to undergo mitosis and meiosis.
3. In spermatogenesis, Meiosis is seen to get going with a cell called the primary spermatocyte.
4. Towards the end of the primary meiotic division, a haploid cell is created called the secondary spermatocyte.
5. This haploid cell goes through another meiotic cell division.
6. The cell created toward the end of meiosis is known as a spermatid.
7. At the point when it arrives at the lumen of the tubule and grows a flagellum (or "tail"), it is known as a sperm cell.
8. Four sperms result from every essential spermatocyte that goes through meiosis.

Oogenesis:

1. Oogenesis is the process through which an ovum differentiates into a cell capable of continuing to grow after fertilization.
2. It grows through maturation from the original oocyte.
3. The embryonic stage is when oogenesis begins.
4. In Oogenesis there is only one ovum is produced due to unequal division of meiosis producing one haploid cell.
5. Mature eggs are produced during female gametogenesis or oogenesis.
6. Meiosis causes 4 haploid cells to divide into a single egg.
7. The initial oocyte goes through its first meiotic division to create a daughter oocyte as oogenesis continues (haploid).
