Assertion: Photosynthetically C4 plants are less efficient than C3 plants.
Reason: The operation of C4 pathway requires the involvement of only bundle-sheath cells.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
(c) If the Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(e) If the Assertion is incorrect but the Reason is correct.
(d) If both the Assertion and Reason are incorrect.
Explanation:
C4 plants are more efficient in picking up CO2 even when it is found in low concentration because of its high affinity for PEP. They show kranz anatomy i.e. vascular bundle is surrounded by bundle sheath and mesopyll cells.
