Which 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.
