← Nature & AnimalsWhich risk increases when some rainforest tree species maintain open stomata during prolonged cloudy periods?
A)Carbon fixation enzyme inhibition occurs
B)Turgor pressure increases due to inflow
C)Xylem embolism risk from decreased pressure✓
D)Reduced ATP for nutrient transport results
💡 Explanation
Increased transpiration occurs because stomata remaining open facilitate water movement; transpirational pull lowers xylem pressure. Therefore, increased xylem embolism risk occurs, rather than other issues related to reduced photosynthesis which require sunlight.
