A) Photorespiration is useful process.
B) \[{{C}_{4}}\]plants are more efficient than\[{{C}_{3}}\]plants.
C) \[{{C}_{3}}\]plants are more efficient than\[{{C}_{4}}\]plants.
D) Photorespiration is absent in\[{{C}_{3}}\]plants but present in\[{{C}_{4}}\]plants.
Correct Answer: B
Solution :
\[{{C}_{4}}\] plants are more efficient than \[{{C}_{3}}\] plants because they have little photorespiration while in \[{{C}_{3}}\] plants more than half of photosynthetic carbon get lost in photorespiration. \[{{C}_{4}}\] plants are more efficient in picking up \[C{{O}_{2}},\] even in low\[C{{O}_{2}}\]concentration because of high affinity of \[C{{O}_{2}}\] with PEP (phosphoenol pyruvic acid).
