NURSING ANM AND GNM

Detailed explanation-1: -The correct answer is To prepare Proteins. All plants absorb nitrogen as NO3 (nitrate ion) from the soil. These are then converted to ammonium ions to combine into amino acids and eventually convert into proteins.

Detailed explanation-2: -Plants use nitrates to make amino acids and proteins; these are then transferred to animals in the food chain .

Detailed explanation-3: -In plants, inorganic nitrogen (i.e. NO3– and NH4+) taken up by roots is incorporated into glutamine and glutamate (primary nitrogen assimilation), which is used to synthesize other amino acids and nitrogenous compounds by transamination.
