NEET · Biology · STD 11 - 11. photosynthesis in higher plants
Given below are two statements: Statement \(I\): In \(\mathrm{C}_3\) plants, some \(\mathrm{O}_2\) binds to \(\mathrm{RuBisCO}\), hence \(\mathrm{CO}_2\) fixation is decreased. Statement \(II\): In \(\mathrm{C}_4\) 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:
- A Both Statement \(I\) and Statement \(II\) are false
- B Statement \(I\) is true but Statement \(II\) is false
- C Statement \(I\) is false but Statement \(II\) is true
- D Both Statement \(I\) and Statement \(II\) are true
Answer & Solution
Correct Answer
(B) Statement \(I\) is true but Statement \(II\) is false
Step-by-step Solution
Detailed explanation
photorespiration does not occur in \(\mathrm{C}_4\) plants as they lack RuBis\(CO\) in mesophy\(ll\). Hence statement \(I\) is the only correct option.
