Oogenesis occurs in the ovaries, specifically within structures called follicles.

Here's a breakdown:

* Ovaries: These are the female reproductive organs responsible for producing eggs (ova).

* Follicles: These are small sacs within the ovaries that contain developing egg cells (oocytes).

* Oogonia: These are the primordial germ cells that divide mitotically to form primary oocytes.

* Primary Oocytes: These cells begin meiosis but become arrested in prophase I until puberty.

* Meiosis: This is the process of cell division that produces haploid egg cells (ova).

So, the journey of oogenesis begins with oogonia in the ovaries, continues within follicles, and culminates in the formation of mature eggs ready for fertilization.
