Nitrogen is an important constituent of living organisms as it an essential part of proteins, amino acids and nucleic acids. The atmosphere contains about 79% nitrogen. Plants and animals cannot assimilate free nitrogen directly from the air.
Nitrogen is the most essential element for living being next to water. It constitutes 78% of earth atmosphere and present at about 10-15% in living protoplasm. These are present in form of proteins, vitamins, chlorophylls, cytochromes, nucleic acid, hormones and functional group of enzymes in plant cell.
Besides water and mineral salts the next important substances of plant cell is proteins and other nitrogenous compounds. Nitrogen is a universally occurring element in all living beings and from the important constituents of cholorophyll, vitamins, hormones, cytochromes, enzymes, nucleic acids and proteins.
