Question

The diploid cells in the testes that undergo meiosis I to produce haploid cells are the ___________.

a. secondary spermatocytes
b. primary spermatocytes
c. interstitial cells
d. spermatogonia
e. Sertoli cells

Answer 1

b. Primary spermatocytes

Step-by-step explanation:

Primary spermatocytes are the diploid cells present in seminiferous tubules of testes. These diploid cells enter meiosis I and produce haploid cells. Each diploid primary spermatocyte produces two haploid cells by meiosis I which are called secondary spermatocytes.

The secondary spermatocytes then enter meiosis II to produce sperms.
