Match the following columns:
| Column I | Column II |
| a. Synthesis of IAA | 1. Magnesium |
| b. Exanthema | 2. Molybdenum |
| c. Anthocyanin | 3. Sulphur |
| d. Nitrogen fixation | 4. Copper |
| 5. Zinc |
Answer & Solution
Correct Answer:
Option
C
a. Synthesis of IAA includes Zinc. Zinc is an important essential micronutrient. Zinc is required for the activity of carbonic anhydrase, and auxin biosynthesis.
b. Exanthema disease is a deficiency symptom of copper in the plant, produced by soil factors and brought about by soil microorganisms, as they attack the roots and produce harmful substances.
c. Anthocyanin and Magnesium. Magnesium treatment caused a significant increase in anthocyanin concentration in all plants, with a stronger effect under elevated temperature regimes.
d. Nitrogen Fixation includes Molybdenum. The molybdenum nitrogenase is responsible for most biological nitrogen fixation, a prokaryotic metabolic process that determines the global biogeochemical cycles of nitrogen and carbon.
