[Solved] A. Under conditions of high light intensity and limited CO2 supply, photorespiration has a useful role in protecting the plants from photo-oxidative damage. R. If enough CO2 is not available to utilize light energy for carboxylation to proceed, the excess energy may not cause damage to plants.

A. The atmospheric concentration of CO2 at which photosynthesis just compensation point. R. The CO2 compensation point is reached when the amount of CO2 uptake is less than that generated through respiration because the level of CO2 in the atmosphere is more than that required for achieving CO2 compensation point.
