The first cells produced by the repeated cell division of germinal epithelium of testis are:
Correct answer: B. Spermatogonia
- A. Interstitial cells
- B. Spermatogonia
- C. Secondary spermatocytes
- D. Spermatids
Explanation
Option [A] interstitial cells are present between the seminiferous tubules of testis and secrete testosterone hormone.Option [B] Each testis consists of seminiferous tubules in which repeated division by cells of the germinal epithelium produce spermatogonia.These increase in size and differentiate into primary spermatocytes.So option B IS RIGHT.Option [C] secondary spermatocytes are formed by meiotic division[ meiosis 1] of primary spermatocytes.Option [D] spermatids are formed by meiosis [meiosis 2] of secondary spermatocytes'
