← Nature & AnimalsWhich outcome results when water temperature increase reduces xylem adhesion?
A)Increased risk of transpiration failure✓
B)Decreased availability of nitrate supply
C)Enhanced mineral absorption efficiency
D)Reduced root respiration rate overall
💡 Explanation
Higher temperatures reduce water's surface tension, affecting xylem vessel walls via cohesion-tension mechanism, because water molecules cannot adhere effectively; therefore, it increases the risk of cavitation and the transpiration failure, rather than improving nutrient supply.
