With reference to factors affecting the rate of photosynthesis, which of the following state- ments is not correct?
Option 1 : Increasing atmospheric CO2 concentration up to 0.05 per cent can enhance CO2 fixation rate.
Option 2 : C3 plants respond to higher temperatures with enhanced photosynthesis while C4 plants have much lower temperature optimum.
Option 3 : Tomato is a greenhouse crop which can be grown in CO2 enriched atmosphere for higher yield.
Option 4 : Light saturation for CO2 fixation occurs at 10 per cent of full sunlight.
