← Nature & AnimalsWhich effect results when high atmospheric ozone concentrations increase photosynthetic rates in plants?
A)Stomata closure reducing CO2 intake✓
B)Increased transpiration leading to wilting
C)Enhanced water-use efficiency increases yield
D)Downregulation of chlorophyll synthesis
💡 Explanation
When ozone concentrations increase, plants initiate stomata closure because ozone damages photosynthetic tissues; this response prevents ozone entry which limits CO2 uptake. Therefore, stomatal closure reduces CO2, rather than increased efficiency, wilting or chlorophyll inhibition which needs specific physiological events instead environmental protection.
