← Nature & AnimalsWhich outcome occurs when high CO2 levels around guard cells?
A)Stomata close to reduce transpiration✓
B)Increased photosynthesis enhancing sugar output
C)Accelerated nutrient uptake from soil
D)Elevated root respiration anaerobic metabolism
💡 Explanation
Stomata close partially because elevated CO2 triggers abscisic acid production causing ion efflux via osmosis; therefore reduced transpiration occurs, rather than continued water loss, and altered photosynthetic rates occur under different conditions.
