← Nature & AnimalsWhich xylem vessel consequence develops under elevated leaf temperatures?
A)Increased viscosity reduces water flow
B)Cavitation obstructs water transport upwards✓
C)Decreased root pressure limits uptake
D)Transpiration rates facilitate nutrient absorption
💡 Explanation
Increased leaf temperature enhances water evaporation rate, forming vapor bubbles. This causes cavitation to disrupt the pulling force in xylem tracheids, because cohesion-tension stalls, and therefore decreases water transport, rather than other effects on root pressure.
