Which pair of cells appear during the process of spermatogenesis?

Options

A. Spermatogonia, sperm lysin
B. Oocyte, Spermatozoa
C. Spematid, Primordial follicle
D. Spermatogonia, Spermatozoa

Answer

To solve the question "Which pair of cells appear during the process of spermatogenesis?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand Spermatogenesis**:
- Spermatogenesis is the process by which sperm cells are produced in the male reproductive system. It occurs in the seminiferous tubules of the testes.

2. **Identify Key Cell Types**:
- The process begins with **Spermatogonia**, which are the germ cells that undergo mitosis to produce primary spermatocytes.
- Primary spermatocytes undergo meiosis to form **secondary spermatocytes**.
- Secondary spermatocytes then further divide to produce **spermatids**.
- Finally, spermatids mature into **spermatozoa** (mature sperm cells).

3. **Evaluate the Options**:
- **Option 1: Spermatogonia and Sperm Glycine** - This is incorrect because sperm glycine is not a cell type involved in spermatogenesis.
- **Option 2: Oocyte and Spermatozoa** - This is incorrect as oocytes are related to oogenesis (egg formation) and not spermatogenesis.
- **Option 3: Spermated and Primordial Follicles** - This is incorrect because primordial follicles are related to female reproductive structures and not spermatogenesis.
- **Option 4: Spermatogonia and Spermatozoa** - This is correct as both of these are directly involved in the process of spermatogenesis.

4. **Conclusion**:
- The correct answer is **Option 4: Spermatogonia and Spermatozoa**. These two types of cells appear during the process of spermatogenesis.
