Iron Deficiency is Often Indicated by Yellowing in Newly Formed

Question

Iron deficiency is often indicated by yellowing in newly formed leaves.This suggests that iron
A)is a relatively immobile nutrient in plants.
B)is tied up in formed chlorophyll molecules.
C)is concentrated in the xylem of older leaves.
D)is concentrated in the phloem of older leaves.
E)is found in leghemoglobin and reduces the amount available to new plant parts.

Accepted Answer

Iron is a relatively immobile nutrient in plants, which means that it does not move easily within the plant. When there is a deficiency, the plant is not able to transport iron to newly formed leaves, resulting in yellowing. The older leaves may contain more iron due to accumulation over time.
