GENERAL KNOWLEDGE

Detailed explanation-1: -A series of amino acids shapes proteins. Plants synthesize, by way of photosynthesis, amino acids from the main elements, carbon and oxygen derived from sunlight, hydrogen from water in the soil that forms carbon hydrate (such as glucose).

Detailed explanation-2: -All proteins of animals and plants are exclusively made of L-amino acids (D-amino acids are extremely rare in nature). Plants can synthesize their own amino acids through chemical reactions using significant expenditures of energy.

Detailed explanation-3: -Amino acids and their derivatives have various prominent functions in plants, such as protein synthesis, growth and development, nutrition and stress responses (Hildebrandt et al., 2015).
