← Nature & AnimalsWhich consequence results when plants experience high vapor-pressure deficit?
A)Increased guard cell turgor pressure
B)Reduced transpiration rates
C)Elevated stomatal closing hormone levels✓
D)Enhanced photosynthetic carbon fixation
💡 Explanation
Elevated vapor-pressure deficits triggers increased abscisic acid (ABA) production, stimulating stomatal closure signals, because hydraulic conductance decreases, therefore increased ABA levels occur, rather than opening, due to dry air stresses.
