Hint: Oogenesis is the process by which the ovum is produced and developed inside the ovary. While ovulation is the process by which the egg is released from the ovary. The cell passes through various stages before finally becoming the ovum.
Complete answer:
To solve the given question, we must first know about oogenesis. The female reproductive system is very complex.
In this process of oogenesis, the oogonia divides forming the primary oocyte. Each primary oocyte then gets surrounded by a granulosa layer and is known as the primary follicle. The primary follicles are then surrounded by new layers and are then called secondary follicles.
The secondary follicle then changes into tertiary follicles. The cavity of this tertiary follicle gets filled with a fluid and is called the antrum. The cell further undergoes division and forms a secondary oocyte and a polar body.
The tertiary follicle now changes into Graafian follicle. The secondary oocyte gets surrounded by zona pellucida. Now the Graafian follicle ruptures and releases the secondary oocyte. The process is known as ovulation.
The diagram given above shows the cross-section of the ovary.
Note:
Oogenesis takes place once in a lifetime during the embryo formation. After this no more oogonia are formed during the lifetime of the female unlike the male reproductive system where the spermatogenesis takes place during the lifetime. Further, in oogenesis polar bodies are formed while in spermatogenesis no polar bodies are formed.
