← Nature & AnimalsWhich outcome occurs when xylem vessels in a tall tree experience significant damage from an ice storm?
A)Reduced leaf water potential✓
B)Increased photosynthetic carbon fixation
C)Enhanced stomatal closure response
D)Elevated translocation of phloem sap
💡 Explanation
Reduced leaf water potential occurs because damage prevents the cohesion-tension mechanism from effectively drawing water up the xylem; therefore water transport is reduced, impacting leaf hydration rather than altering carbon fixation pathways because water can't reach the leaves.
