A Mineral Deficiency is Likely to Affect Older Leaves More

Question

A mineral deficiency is likely to affect older leaves more than younger leaves if
A) the mineral is a micronutrient.
B) the mineral is very mobile within the plant.
C) the mineral is required for chlorophyll synthesis.
D) the mineral is a macronutrient.

Accepted Answer

If the mineral is very mobile within the plant, it will be transported from older leaves to younger leaves, so the younger leaves will still have adequate levels while the older leaves will show signs of deficiency.
