Question

Identify the incorrect pair:
I. Zinc - ABA Synthesis
II. Boron - Cell elongation
III. Nickel - Urease activator
IV. Molybdenum - Carbohydrate translocation

Hint:

Memorize micronutrient functions: Zn, Ni, Mo, B.
Link nutrient → enzyme or process.
Use table format to quickly identify incorrect pair.

Answer 1

1. Zinc → required for enzyme activation, not directly ABA synthesis.
2. Molybdenum → cofactor for nitrate reductase, not carbohydrate translocation.
3. Boron and Nickel pairs are correct.
4. Hence incorrect pairs: I & IV → (3) I & IV.
