← Nature & AnimalsWhich risk increases when desert plant stomata remain open for extended periods?
A)Xylem embolism from amplified transpiration✓
B)Photoinhibition from escalated light absorption
C)Nutrient deficiency from reduced rubisco efficiency
D)Oxidative stress from increased photorespiration
💡 Explanation
When stomata remain open, increased transpiration occurs because of the concentration gradient between the leaf and the surrounding atmosphere, drawing water through the xylem and potentially leading to cavitation as tension increases. Therefore, xylem embolism becomes more likely, rather than other issues which require independent mechanisms.
