When subjected to high temperatures, which consequence follows elevated transpiration in plants?

A)Increased risk of xylem embolism
B)Decreased photosynthetic carbon fixation
C)Enhanced nutrient uptake efficiency
D)Reduced susceptibility to pathogen infection

💡 Explanation

Higher temperatures cause the stomata to open wider, increasing transpiration, and creating more tension within the xylem vessels activating cavitation; therefore, increasing the risk of xylem embolism, rather than aiding in carbon fixation because the tension will damage the xylem.
