Which increased risk arises due to blocked stomata during high-intensity transpiration streams?

A)Increased rate of photorespiration
B)Uncontrolled cellular respiration increase
C)Xylem cavitation threshold exceedance
D)Decreased phloem translocation efficiency

💡 Explanation

Blocked stomata increase leaf temperature, intensifying transpiration demands while simultaneously impeding water influx. This induces increased tension on the xylem, thereby facilitating air bubble formation via cavitation because exceeding tension thresholds leads to xylem blockage rather than other cellular dysfunctions.
