Which risk increases when some rainforest tree species maintain open stomata during prolonged cloudy periods?

💡 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.
