Nettetproteins and nucleic acids. Based on this, the main observed effect of nitrogen deficiency in plants has been stunted growth. Nitrogen is employed in the formation of chlorophyll, so it is necessary to move nitrogen from the lower leaves to the higher leaves, which will have a better chance of catching more sunlight for photosynthesis. NettetNitrogen-fixing plant species may respond more positively to elevated atmospheric carbon dioxide concentrations ([CO2]) than other species because of their ability to maintain a high internal nutrient supply. A key factor in the growth response of trees to elevated [CO2] is the availability of nitro … NettetNitrogen is an essential nutrient for plant growth, development and reproduction.
