Assertion: Photorespiration is found in all plants.
Reason : In plants, first fixation product is formed in bundle sheath cells.
Reason : In plants, first fixation product is formed in bundle sheath cells.
View answer and explanation
Correct option: D
Both assertion and reason are incorrect
Option D (Both assertion and reason are incorrect) is correct because photorespiration is NOT found in all plants (it's minimized in C4 plants), and the first CO2 fixation product in C4 plants is formed in mesophyll cells, not bundle sheath cells.
