Given below are two statements: Statement I: In C₃ plants, some O₂ binds to RuBisCO, hence CO₂ fixation is decreased. Statement II: In C₄ plants, mesophyll cells show very little photosynthesis while bundle sheath cells do not show photorespiration. In the light of the above statements, choose the correct answer from the options given below:
To solve this problem, we need to analyze the given statements:Statement I: In C₃ plants, some O₂ binds to RuBisCO, hence CO₂ fixation is decreased. - C₃ plants use the enzyme RuBisCO for carbon fixation. - RuBisCO can bind to both CO₂ and O₂. When O₂ binds, it leads to a process called photorespiration, which decreases the efficiency of CO₂ fixation. - Therefore, Statement I is true.Statement II: In C₄ plants, mesophyll cells show very little photosynthesis while bundle sheath cells do not show photorespiration.
