HORTICULTURE

Detailed explanation-1: -Glucose is joined with nitrates absorbed from the soil to make amino acids . These are joined together to make proteins during protein synthesis . Glucose is also converted to lipids, which is often stored in seeds.

Detailed explanation-2: -As nitrate is assimilated via conversion to nitrite, then ammonium into amino acids, it has been suggested that the internal pools of amino acids within plants may indicate nitrogen status by providing a signal that can regulate nitrate uptake by the plant.

Detailed explanation-3: -Plants use nitrates to make amino acids and proteins; these are then transferred to animals in the food chain .

Detailed explanation-4: -The use of glucose and nitrate ions to form amino acids which in turn are used to synthesise proteins. Respiration. Breakdown of excess proteins to form urea for excretion.

Detailed explanation-5: -Plants produce glucose through photosynthesis. Elements from glucose chemically react with nitrogen compounds to produce amino acids. Amino acids are the building blocks of protein. The images show the makeup of starch and protein.
