← Nature & AnimalsWhich adaptation ensures plants thrive in nitrogen-poor soils?
A)Nodule formation via nitrogen fixation✓
B)Increased xylem vessel diameter
C)Enhanced root hair surface area
D)Accelerated leaf senescence process
💡 Explanation
Nodule formation ensures plant survival in nitrogen-poor soils because symbiotic bacteria perform nitrogen fixation, converting atmospheric nitrogen into usable forms. The plant uses this fixed nitrogen to produce proteins rather than relying solely on soil nitrogen availability.
