alleryMacronutrients in plants are required:
AIn trace amounts only (parts per million)
BOnly during the seed stage of growth
CIn large quantities (> 10 mmol/kg dry weight)
DOnly by C4 plants (not by C3 plants)
Answer & Solution
Correct answer: C. In large quantities (> 10 mmol/kg dry weight)
Macronutrients (N, P, K, S, Ca, Mg, C, H, O) are required in LARGE quantities (> 10 mmol/kg).
Micronutrients (Fe, Mn, Cu, Mo, Zn, B, Cl, Ni) in trace amounts. Both equally essential.
