NEET BIOLOGY

Detailed explanation-1: -Nitrogen is introduced to the soil by fertilizers or animal and plant residues. Bacteria in the soil convert the nitrogen to ammonium and nitrate, which is taken up by the plants by a process of nitrogen fixation. In order to make amino acids, proteins, and DNA plants need nitrogen.

Detailed explanation-2: -Nitrogen Is Key to Life! When plants do not get enough nitrogen, they are unable to produce amino acids (substances that contain nitrogen and hydrogen and make up many of living cells, muscles and tissue). Without amino acids, plants cannot make the special proteins that the plant cells need to grow.

Detailed explanation-3: -Plants synthesize their own amino acids from inorganic nitrogen. The process includes the transformation of nitrate into nitrite and ammonium, and eventually into an organic molecule resulting in glutamic acid.

Detailed explanation-4: -Plant cells require sulfate and nitrate molecules that serve as the reservoir of sulfur and nitrogen, that are accountable for driving the conversion of glucose molecules to create amino acids and further protein.

Detailed explanation-5: -Glucose is joined with nitrates absorbed from the soil to make amino acids . These are joined together to make proteins during protein synthesis .
