Match List-I with List-II
Column I
- A. Iron
- B. Zinc
- C. Boron
- D. Molybdenum
Column II
- I. Synthesis of auxin
- II. Component of nitrate reductase
- III. Activator of catalase
- IV. Cell elongation and differentiation
Correct answer: A → III, B → I, C → IV, D → II
Explanation
Iron activates catalase, zinc is needed for auxin synthesis, boron for cell elongation, and molybdenum for nitrate reductase.
Detailed Solution
Iron: It activates catalase enzyme, and is essential for the formation of chlorophyll.
Zinc: It is needed in the synthesis of auxin.
Boron: It is required for uptake and utilisation of $Ca^{2+}$, cell elongation, cell differentiation, membrane functioning, pollen germination and carbohydrate translocation.
Molybdenum: It is a component of several enzymes, including nitrogenase and nitrate reductase.
