← Nature & AnimalsWhich outcome occurs when cut deciduous tree branches, submerged in water, experience cavitation?
A)Rapid osmotic dehydration near cut
B)Reduced xylem sap cohesive strength✓
C)Refilling of embolized xylem vessels
D)Accelerated phloem transport of sugars
💡 Explanation
Cavitation introduces air bubbles, disrupting the water's continuity within the xylem by breaking weak hydrogen bond attractions; weakening the cohesion-tension mechanism. Therefore, tension reduces, rather than maintains water flow because root pressure alone becomes insufficient.
