Which of the following statements is correct regarding the diagrammatic sectional view of a seminiferous tubule?
Options
- ASertoli cells provide nutrition to the developing sperms.
- BSpermatids undergo meiosis to form spermatocytes.
- CSpermatogonia are found in the interstitial spaces.
- DPrimary spermatocytes are haploid cells.
Correct answer
A. Sertoli cells provide nutrition to the developing sperms.
Step-by-step solution
The Sertoli cells provide nutrition to the germ cells. The regions outside the seminiferous tubules called interstitial spaces, contain small blood vessels and interstitial cells or Leydig cells. Each seminiferous tubule is lined on its inside by two types of cells called male germ cells (spermatogonia) and Sertoli cells. Each spermatogonia is diploid and contains 46 chromosomes. Some of the spermatogonia called primary spermatocytes periodically undergo meiosis.
