NEET 2024 Botany C3 vs C4 Plants Assertion Reason Question
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 photorespiration while bundle sheath cells do not show photorespiration.
In the light of the above statements, choose the correct answer from the options given below:
Statement I is true but Statement II is false
Statement I is false but Statement II is true
Both Statement I and Statement II are true
Both Statement I and Statement II are false
Correct Answer
Detailed Explanation
In C₃ plants, O₂ competes with CO₂ for RuBisCO, reducing CO₂ fixation. C₄ plants minimize photorespiration by spatially separating initial CO₂ fixation and the Calvin cycle.
