Spermatogonia undergo a series of cell divisions statements to produce sperms. Select the correct from the following :

A. Spermatogonia always undergo meiotic cell division.

B. Primary spermatocytes divide mitotically to produce secondary spermatocytes.

D. Spermatids produce spermatozoa through mitosis.

E. Spermatids transform into spermatozoa by spermiogenesis.

Choose the correct answer from the options given below:

Accepted Answer

B. 1. **Check statement A.**

Spermatogonia are diploid cells present in the testis. They first multiply by **mitotic division** to increase their numbers before some of them undergo further changes to become primary spermatocytes. So spermatogonia do **not** always undergo meiotic division — Statement A is incorrect.

2. **Check statement B.**

Once formed, a spermatogonium increases in size and becomes a **primary spermatocyte**. This primary spermatocyte then undergoes the **first meiotic division (meiosis I)**, not mitosis, to produce two **secondary spermatocytes**. So Statement B, which says this division is mitotic, is incorrect.

3. **Check statement C.**

Each secondary spermatocyte undergoes the **second meiotic division (meiosis II)**, producing **haploid spermatids**. This matches the biology correctly, so Statement C is correct.

4. **Check statement D.**

Spermatids do not become spermatozoa through mitosis — instead, they undergo a special transformation process. So Statement D is incorrect.

5. **Check statement E.**

The process by which spermatids transform into mature, motile spermatozoa is called **spermiogenesis**. This is correctly stated, so Statement E is correct.

6. **Conclusion.**

Only statements C and E are correct.

Hence, the answer is **B**.
