Solution
| Column I | Column II | ||
| (a) | Leydig Cells | 3. | Testosterone |
| (b) | Stoma | 4. | Diffusion of respiratory gases |
| (c) | Ova | 5. | Haploid cells |
| (d) | Cranial nerve | 2. | 12 pairs |
| (e) | Cretinism | 1. | Lack of thyroxine in children |
Explanation:
- Leydig cells: The main function of these cells is to secrete androgens, such as testosterone (a male sex hormone).
- Stoma: The stoma facilitates gas transfer between the plant's leaves and the atmosphere.
- Ova: These are female gametes, which are haploid.
- Cranial nerves: Higher vertebrates have twelve pairs of cranial nerves.
- Cretinism: It is a disorder that causes aberrant mental and physical growth in children as a result of a shortage of thyroid gland hormones, or thyroxine.
