← Nature & AnimalsWhich outcome occurs when a palm tree experiences prolonged exposure to intense heat with limited water availability?
A)Xylem tension induces leaf abscission✓
B)Increased root pressure avoids cavitation
C)Decreased transpiration lowers stem turgor
D)Phloem reverses to dilute xylem sap
💡 Explanation
Xylem tension increases during transpiration as water evaporates, but severe stress causes cavitation. Leaf abscission occurs because reducing leaf surface area decreases transpiration, therefore minimizing water loss rather than maintaining it.
