With reference to factors affecting the rate of photosynthesis, Which of the following statements is not correct?
1 Increasing atmospheric \(C{O_2}\) concentration up to \(0.05\% \) can enhance \(C{O_2}\) fixation rate
2 \({C_3}\) plants respond to higher temperatures with enhanced photosynthesis while \({C_4}\) plants have much lower temperature optimum
3 Tomato is a greenhouse crop which can be grown \(C{O_2}\) - enriched atmosphere for higher yield
4 Light saturation for \(C{O_2}\) fixation occurs at \(10\% \) of full sunlight
Explanation:
In \({C_3}\) plants, due to increased photorespiration, photosynthesis is decreased at higher temperature. \({C_4}\) plants have higher temperature optimum because of the presence of pyruvate phosphate dikinase enzyme, which is sensitive to low temperature.
