Match the following:
Column - I Column - II
A.Manganese 1. Involved in electron transport
B.Copper 2. Role in Nitrogen fixation
C.Boron 3. Photolysis of water
D.Molybdenum 4. Maintenance of ionic balance in cells
5. Required for pollen germination
A - 3, B - 1, C - 5, D - 2
The function of Mn (micronutrient) is in the splitting of water to liberate oxygen during photosynthesis. Copper is involved in the electron transport during aerobic respiration. Boron is required for pollen germination in plants. Molybdenum is a component of enzyme nitrogenase which is required for nitrogen fixation in legume plants (like soybeans, peanuts, tamarind).
