Which outcome occurs when light intensity increases significantly above the optimum for C3 plant photosynthesis?

💡 Explanation

When light intensity exceeds optimum, excess energy absorbed by chlorophyll results in increased ROS production, because rubisco begins to inactivate at high fluxes with stomatal closure. Thefore ROS production results, rather decreases photorespiration, increasing carbon fixation, or reduced transpiration, which involves increased carbon assimilation requirements.
