← Nature & AnimalsWhich plant outcome commonly results when molybdenum availability constrains nitrogenase?
A)Reduced photosynthetic rate occurs✓
B)Enhanced xylem vessel formation acts
C)Increased calcium uptake occurs
D)Accelerated lignin deposition occurs
💡 Explanation
A molybdenum deficiency limits nitrogenase, impairing nitrogen fixation needed for chlorophyll synthesis; therefore, reduced photosynthetic rate results, because nitrogen limitation hinders chlorophyll rather than affecting structural elements like xylem, lignin, or calcium other metabolic functions.
