Question

Match List I with List II:

| | List I | | List II |
|---|---|---|---|
| (A) | Iron | (I) | Synthesis of auxin |
| (B) | Zinc | (II) | Component of nitrate reductase |
| (C) | Boron | (III) | Activator of catalase |
| (D) | Molybdenum | (IV) | Cell elongation and differentiation |

Choose the correct answer from the options given below:

Accepted Answer

B. 1. **Recall micronutrient functions** - Each micronutrient in plants performs a specific biochemical role.

2. **Match Iron** - Iron is essential for chlorophyll synthesis and also acts as an activator of the enzyme catalase. So, (A) Iron matches (III) Activator of catalase.

3. **Match Zinc** - Zinc is required for the synthesis of the plant growth hormone auxin (IAA). So, (B) Zinc matches (I) Synthesis of auxin.

4. **Match Boron** - Boron is essential for cell elongation, differentiation, and pollen germination. So, (C) Boron matches (IV) Cell elongation and differentiation.

5. **Match Molybdenum** - Molybdenum is a component of the enzyme nitrate reductase, which reduces nitrate to nitrite. So, (D) Molybdenum matches (II) Component of nitrate reductase.

6. **Conclusion** - Putting it together: A-III, B-I, C-IV, D-II. Hence, the answer is **Option B**.
