With reference to factors affecting the rate of photosynthesis, which of the following statements is not correct?
Increasing atmospheric CO2 concentration up to 0.05% can enhance the CO2 fixation rate
C3 plants respond to higher temperatures with enhanced photosynthesis while C4 plants have much lower temperature optimum
Tomato is a greenhouse crop that can be grown in CO2 enriched atmosphere for higher yield
Light saturation for CO2 fixation occurs at 10% of full sunlight
C4 plants respond to higher temperatures and show higher rates of photosynthesis, while C3 plants have a much lower temperature optimum . The statement in Option B is incorrect because it claims C4 plants have a lower temperature optimum. The other statements are correct: CO2 concentration up to 0.05% enhances fixation ; Tomatoes are C3 plants used in greenhouses for higher yields ; Light saturation occurs at 10% of full sunlight .
