← Nature & AnimalsWhich limiting consequence occurs in environments with high atmospheric ozone concentrations on plant function through stomata?
A)Accelerated CO2 uptake efficiency increases
B)Photosynthetic damage and reduced growth✓
C)Enhanced nutrient transport to root system
D)Increased water use efficiency improves yield
💡 Explanation
When high ozone enters through stomata, oxidative stress is induced because ozone decomposes into reactive oxygen species (ROS) within mesophyll cells, damaging photosynthetic machinery. Therefore photosynthetic damage reduces plant growth, rather than CO2 uptake, nutrient transport, or water efficiency which would prevent/reverse damage.
