Which of the statements is not true of the C_(4) pathway

C_(4) plants are more efficient in photosynthesis than C_(3) plants due to

Assertion: Photosynthetically C_(4) plants are less efficient than C_(3) plants. Reason: The operation of C_(4) pathway requires the involvement of only bundle-sheath cells.

Consider the two 'postulates' gives below: (i) Given any two distinct points A and B, there exists a third point C, which is between A and B. (ii) There exist at least three points that are not on the same line. Do these postulates contain any undefined terms? Are these postulates consistent? Do they follow from Euclid's postulates? Explain.

Asserotion: C_(4) photosynthetic pathway is more efficient than the C_(3) pathway. Reson : Photorespirationis suppressed in C_(4) plants.

Consider the following statement: A.The layer of bundle sheath cells in the leaves of C_(4) plants lacks intercellular spaces- B. The bundle sheath cells in the leaves of C_(4) plants lack mitochondria and peroxisomes.- C. The bundle sheath cells of C_(4) plants have large number of chloroplasts and thick walls.- Neither C_(4) plants nor CAM plants have grana in their chloroplasts and thick walls. - Which of the statements given above is/are correct?
