Solution(By Examveda Team)

Iron deficiency in the plant is characterized by the Yellowing of new leaves.
The distinctive symptom of iron deficiency is the chlorosis of the youngest leaves. As chlorosis is a result of photobleaching, leaves in bright sunlight will be more affected than those in shade.
Initially, yellow interveinal chlorosis develops, which is characterized by a sharply contrasting green network of veins. Iron is needed to produce chlorophyll, hence its deficiency causes chlorosis.
