← Nature & AnimalsWhich risk increases when stomata close during wilting?
A)Phloem transport becomes more efficient
B)Rate of transpiration decreases greatly
C)Photorespiration rate will then dramatically increase✓
D)Active transport proceeds unimpeded into mesophyll
💡 Explanation
Stomata closure due to wilting causes higher O₂ concentration because the Calvin cycle halts, therefore photorespiration rises due to less CO₂ available for carbon fixation, rather than efficient phloem or unaffected active transport.
