Which one among the following is not a micronutrient for plants?

Correct option is C

The correct answer is (c) Magnesium. Magnesium is not a micronutrient for plants; it is a macronutrient. Plants need macronutrients in larger quantities for their growth and development. Magnesium plays a central role in the chlorophyll molecule, which is essential for photosynthesis. It also helps in enzyme activation. In contrast, micronutrients are required in smaller amounts.
Information Booster: ● Iron (Fe): A micronutrient essential for chlorophyll formation and various enzymes. ● Manganese (Mn): A micronutrient that helps in photosynthesis and enzyme activation. ● Magnesium (Mg): A macronutrient, not a micronutrient, crucial for the chlorophyll structure. ● Chlorine (Cl): A micronutrient needed for ionic balance and photosynthesis. ● Micronutrients are required in trace amounts, while macronutrients are needed in larger quantities. ● Examples of other macronutrients include Nitrogen, Phosphorus, and Potassium.
