NURSING ANM AND GNM

Detailed explanation-1: -Plants can absorb nitrate or nitrite from the soil via their root hairs. If nitrate is absorbed, it is first reduced to nitrite ions and then ammonium ions for incorporation into amino acids, nucleic acids, and chlorophyll.

Detailed explanation-2: -Plants take up nitrate from the soil via the transporter proteins present in the root cell membrane. There are other nitrate transporters that are involved in moving nitrate within plants to different tissues as needed.

Detailed explanation-3: -Nitrate is a naturally occurring chemical form of nitrogen found in most soils. Nitrate may be formed when plant residues, animal manures and human wastes decompose. It may be added to soil directly as a nitrogen fertilizer.

Detailed explanation-4: -Plants absorb ammonium and nitrate during the assimilation process, after which they are converted into nitrogen-containing organic molecules, such as amino acids and DNA.
