Answer» Correct Answer - C Nitrogen is the constituent of amino acids, proteins, nucleic acids, nucleotides, coenzmes, hexosamines nucleic acids, nucleotides, coenzymes, hexosamines etc. Deficiency of nitrogen rapidaly inhibits the plant growth and yellowing of the leaves (chlorosis) magnesium has the specific role in the activation of enzymes, taking part in photosynthesis and respiration. It also forms a part of the ring structure of the chlorophyll molecule. Deficiency of Mg causes chlorosis i.e., yellowing of leaves. Thus a plant growing in magnesium-deficient soil would show chlorosis inspite of being sprayed with urea (nitrogen). |
