← Nature & AnimalsWhich outcome impacts tall tree water transport when soil dries significantly?
A)Increased cavitation within xylem vessels✓
B)Enhanced stomatal opening for photosynthesis
C)Elevated root respiration and ATP use
D)Decreased phloem osmotic pressure gradient
💡 Explanation
Soil drying increases tension, and the resulting air bubbles induce cavitation within the water columns inside xylem vessels. This hinders water's upward movement because cohesion-tension relies on continuous liquid columns, rather than vapor lock disrupting it.
