Which outcome occurs when xylem walls weaken in tall trees?

💡 Explanation

Increased cavitation occurs because weakened xylem causes a reduction in xylem structural integrity, leading to increased tension and possible vessel collapse due to loss in cohesion and adhesion, which makes cavitation more likely rather than maintaining water flow.
