AIIMS 2006 Botany Photorespiration Assertion Reason Question
Type: Assertion Reason-conceptual-Medium-Class 11
Assertion : Under conditions of high light intensity and limited CO₂ supply, photorespiration has a useful role in protecting the plants from photo-oxidative damage.
Reason : If enough CO₂ is not available to utilize light energy for carboxylation to proceed, the excess energy may not cause damage to plants.
A
Both Assertion and Reason are true and Reason is the correct explanation of Assertion
B
Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
C
Assertion is true but Reason is false
D
Both Assertion and Reason are false
Correct Answer
Option C
Detailed Explanation
