Question

Identify the incorrect match from the following

• A. Chlorine - helps in oxygen evolution
• B. Boron - Pollen germination
• C. Molybdenum - Carbohydrate translocation
• D. Zinc - Auxin synthesis

Answer 1

The correct option is C Molybdenum - Carbohydrate translocation

Plants require boron for pollen germination, calcium uptake and its utilization, cell elongation, cell differentiation, proper functioning of membrane and carbohydrate translocation.
Several enzymes required for nitrogen metabolism such as nitrogenase & nitrate reductase contain molybdenum.

Chlorine helps determine solute concentration as well as ionic balance in cells along with sodium and potassium ions. It is also required for water splitting reaction in photosynthesis that eventually leads to evolution of oxygen.
Zinc activates enzymes like carboxylases and is involved in biosynthesis of hormones like auxin.
