With reference to factors affecting the rate of photosynthesis, which of the following statements is not correct?
- ALight saturation for CO
2
fixation occurs at 10% of full sunlight - BIncreasing atmospheric CO
2
concentration upto 0.05% can enhance CO
2
fixation rate - CC3 plants responds to higher temperatures with enhanced photosynthesis while C4 plants have much lower temperature optimum
- DTomato is a greenhouse crop which can be grown in CO
2
- enriched atmosphere for higher yield
Solution & Step-by-step Explanation
Statement C is incorrect. C4 plants are adapted to tropical climates and have a higher temperature optimum. C3 plants have a lower temperature optimum and suffer from photorespiration at high temperatures, which reduces their photosynthetic rate.
