Question
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 .
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Photosynthesis in Higher Plants . Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
