Which of the following nutrient is incorrectly paired with its function in plant?
Correct answer: B. Molybdenum cell permeability
- A. Iron-cytochromes and chlorophyll
- B. Molybdenum cell permeability
- C. Cobalt- Required by nitrogen fixers
- D. Calcium- formation of cell wall.
Explanation
Molybdenum is an essential component in two enzymes that convert nitrate into nitrite (a toxic form of nitrogen) and then into ammonia before it is used to synthesize amino acids within the plant. It is also needed by symbiotic nitrogen fixing bacteria in legumes to fix atmospheric nitrogen. So it cannot be used in cell permeability thus option b is incorrect.
