NEET BIOLOGY

Detailed explanation-1: -Micronutrients are trace elements such as vitamins and minerals. They differ from macronutrients, like carbohydrates, protein and fat, because they are necessary only in very small amounts, generally, these are utilized by plants as cofactors for certain enzymes, eg Mo for nitrogenase.

Detailed explanation-2: -Macronutrients such as nitrogen, potassium, and sulfur are mobile in plants. Therefore, micronutrients are immobile and required in tiny amounts from the soil.

Detailed explanation-3: -Enzymes lower the amount of activation energy needed for a reaction and in turn speed up reactions. Some micronutrients like, Vitamin B9, are used as coenzymes in reactions throughout the body. Micronutrients that are cofactors and coenzymes bind enzymes to substrates, and without them cell metabolism would stop.

Detailed explanation-4: -they play only a minor role in the growth and health of the plant.

Detailed explanation-5: -Micronutrients are the nutrients that are required by plants in small amounts or quantities. E.g., Zinc, iron, copper, manganese, molybdenum, etc.
