← Nature & AnimalsWhich effect results when xylem pressure sharply decreases?
A)Increased water molecule cohesion
B)Greater mineral ion absorption
C)Cavitation within xylem conduits✓
D)Enhanced rate of leaf transpiration
💡 Explanation
Cavitation causes embolisms due to decreased pressure and disrupted cohesion. The cohesion-tension mechanism gets interrupted, because the xylem's structural integrity decreases, therefore leading to blocked water transport, rather than enhanced transport or molecular cohesion.
