← Nature & AnimalsWhich consequence results when a vascular plant experiences negative pressure gradients surpassing cavitation threshold?
A)Uncontrolled phloem sap backflow results.
B)Xylem embolism blocks water transport.✓
C)Increased turgor will damage cells.
D)Increased root hydraulic conductivity happens.
💡 Explanation
When the negative pressure drops too low, cavitation occurs because then dissolved gasses in the xylem fluid nucleate and expand causing xylem embolism, therefore disrupting the water column, rather than improving conduction or impacting sugar transport.
