1.	Increase in CO2 concentration up to 0.5% causes an increase in photosynthesis. True or false?(a) True(b) FalseThe question was posed to me in a job interview.I'd like to ask this question from Factors Affecting Photosynthesis in chapter Photosynthesis in Higher Plants of Biology – Class 11
Answer» CORRECT option is (B) False Easy EXPLANATION: Increase in CO2 concentration up to 0.05% causes an increase in photosynthesis. If the carbon dioxide concentration increases BEYOND this level, it can become damaging for the plant over long periods.
