← Nature & AnimalsWhich outcome follows when drought raises leaf temperature?
A)Reduced transpiration rate from stomatal closure✓
B)Increased water uptake via root pressure
C)Elevated abscisic acid amplifies guttation
D)Enhanced nutrient transport throughout the phloem
💡 Explanation
Stomatal closure reduces water loss because elevated temperature prompts guard cells to plasmolyze, using abscisic acid to trigger closure, which inhibits transpiration rate, therefore conserving water rather than escalating water uptake because root pressure is negligible.
