Question

Assertion : Photorespiration is found in all plants

Reason : In C4 plants, first ${\mathrm{CO}}_2$ fixation product is formed in bundle sheath cells

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is not correct explanation of A
• C. A is true but R is false
• D. A and R are false

Answer 1

The correct option is C A is true but R is false

Photorespiration does take place in all plants. Many plants have ways to counter it. In the C4 pathway, initial carbon fixation takes place in mesophyll cells and the Calvin cycle takes place in bundle-sheath cells.
Therefore assertion is true but reason is false.
