Which consequence results when a plant experiences excessive water loss that overcomes xylem transport mechanics?

💡 Explanation

Cavitation occurs because the cohesion-tension mechanism relies on continuous water columns; xylem pressure decreases exceed thresholds, therefore breaking the tensile strength of the water column, rather than stomatal closure or other nutrient disruptions under turgor reduction.
