Vedclass · Answer

(A) Elements that are actively mobilized within the plants,such as Nitrogen $(N)$,Potassium $(K)$,and Magnesium $(Mg)$,show deficiency symptoms first in older (senescent) leaves because they are transported to younger,developing parts.Elements that are relatively immobile,such as Sulfur $(S)$ and Calcium $(Ca)$,do not get transported out of mature organs; therefore,their deficiency symptoms appear first in young leaves.Thus,$P$ (young leaves) corresponds to $S$ and $Ca$,and $Q$ (older leaves) corresponds to $N$,$K$,and $Mg$.

Deficiency symptoms of mineral elements appear first in young leaves. - $P$
Deficiency symptoms of mineral elements appear first in senescent (older) leaves. - $Q$
