Which outcome occurs when high CO2 levels around guard cells?

💡 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.
