Explanation of Solution

Every living organism requires essential nutrients for growth and multiplication. The elements essential for plant growth are listed below:

Micronutrients: Chlorine, boron, zinc, iron, manganese, copper, nickel, and molybdenum are the micronutrients because these are essential and required in fewer amounts.

Macronutrients: Macronutrients are obtained from soil and water. Hydrogen, carbon, and oxygen are the elements obtained from the water. Nitrogen, calcium, magnesium, potassium, phosphorus, and sulfur are obtained from soil.

The functions of the macronutrients are as follows:

  • These elements are involved in osmosis.
  • These are the components of the chlorophyll molecules.

The functions of the micronutrients are as follows:

  • These elements are involved in the ionic balance in every plant reactions.
  • These are the activators for some enzymes.
  • These are involved in the nitrogen fixation process.
