Question

Give a basic difference between spermatogenesis and oogenesis.

Answer 1

Hint: It is the process of formation of sperm and it occurs in the seminiferous tubule of sperm. It includes the formation of spermatids and the formation of spermatozoa. And it is the process of formation of the mature female gamete, it occurs in the ovaries.

Complete answer:

Spermatogenesis	Oogenesis
Spermatogenesis is the process of formation of mature sperm s through a series of mitotic and meiotic divisions alongside metamorphic changes within the immature sperm cell.	Oogenesis is the process of formation of a female gamete or ovum through a series of mitotic and meiotic divisions occurring in the female reproductive system.
It is the male type of gametogenesis which brings about the formation of mature male gametes.	It is the female type of gametogenesis which brings about the formation of mature male gametes.
The process of spermatogenesis is completed through the following three-phase; spermatocytogenesis, spermatogenesis, and spermiogenesis.	The process of oogenesis is divided into three-phase; the follicular phase, the ovulation phase, and the luteal phase.
The overall process of spermatogenesis occurs within the testes until the sperm moves to the epididymis and gains motility.	The overall process of oogenesis occurs within the ovary until the mature ovum moves to the fallopian tube.
Spermatogenesis forms millions of sperms every day.	Oogenesis releases one ovum per month.
The primary spermatocyte is the starting cell during spermatogenesis.	The primary oocyte is the starting cell during oogenesis.

Additional Information: The process of spermatogenesis is regulated by different glands and their products. The luteinizing hormone (LH) by the pituitary gland regulates the formation of sperm and therefore the production of testosterone within the male reproductive system.
The ovum which is produced is non-motile and remains in the fallopian tube to be fertilized by the sperm. It is an oval structure that contains yolk or plasma that provides nutrients to the cell.

Note: The method of spermatogenesis is the basis for sexual reproduction which allows genetic recombination, leading to genetic variation among the species.
In animals, oogenesis is a biologically vital process that ensures sexual reproduction. In the newborn baby, it is responsible for the transfer of half of the chromosomes to be introduced.
