Which element is a plant macronutrient?

• A. Magnesium
• B. Iron
• C. Manganese
• D. Zinc

Answer: (A)

Macronutrients are the elements plants need in larger amounts than micronutrients. Magnesium fits this category because it is required in relatively high quantities and plays several core roles in plant physiology. It is the central atom in chlorophyll, so it’s essential for photosynthesis, and it also acts as a cofactor for many enzymes and helps with energy transfer and stabilizing ribosome structure. The other elements listed are micronutrients, needed in much smaller amounts, yet still essential for proper enzyme function and metabolic processes. Iron, manganese, and zinc each support various enzymatic activities and electron transport with that limited, trace-level requirement.
