← Nature & AnimalsWhich outcome occurs when vessel element cavitation interrupts cohesion-tension?
A)Decreased nutrient concentration in the xylem✓
B)Increased root pressure pushes water
C)Stomata closes to reduce cavitation
D)Uncontrolled evaporation from the leaf pores
💡 Explanation
Decreased xylem sap nutrient transport occurs because the cohesion-tension mechanism for water potential relies on uninterrupted hydrogen bonds; cavitation breaks this tensile force. Root pressure helps some, but is too weak, therefore nutrient concentration decreases, rather than maintaining flow through stomatal closure.
