Which consequence results when excessive heat reduces atmospheric humidity affecting water supply to high-altitude vascular plants?

💡 Explanation

Reduced humidity causes greater transpiration, creating runaway water loss, because evaporative cooling, normally facilitated by transpiration, becomes insufficient; therefore, the plant overheats, rather than benefiting from reduced vascular tension or altered stomatal function.
