The invention of a synthetic cell
I believe the correct answer is mantle. Let's hope this is right!
Answer:
The Gonads.(granulosa and sertoli cells)
Explanation:
These are the sources of inhibin in the Gonads. Specifically, the granulosa cells of the female ovaries produced these hormones,while the sertoli cells in testes of males performed the same secretions.
These hormone exits in two forms as Inhibin A and B. Generally, FSH control the granulosa cells and sertoli cells functions and activities.Thus the role of these hormone is to use negative feedback mechanism to control the influence of the FSH on the gonads.
Generally the Oocyte that is lodged in the primordial ovarian follicle is covered by a single layer of cells which are formed from the ovarian surface epithelium,These cells layers are called the Granulosa cells.
The major function is the secretion of oestrogen,under the influence of FSH.It is this activity that is controlled by the Inhibin hormone.

Mitochrondria of the eukaryotic cells.
<span>As many researchers hypothesize that the old single-celled organism or the origin of the complex-celled organisms came from the endosymbiosis of the mitochrondrion organism and the prokaryotic cell. It has been said that mitochondria was an independent organism which then to have been evovled itself after planting itself inside a prokaryotic cell which aided cellular respiration and production of ATP (Adenosine Triphosphate). This then aided the prokaryotic cell to be more sophisticated and caused another change from having without a true nucleus to a eukaryotic cell with a nucleus and embedded DNA. </span>
