A process that makes important difference between C3 and C4 plants is:
Options
(a) Transpiration
(b) Glycolysis
(c) photosynthesis
(d) Photorespiration
Correct Answer:
Photorespiration
Explanation:
Photorespiration is absent is C₄ plants photorespiration does not produce energy or reducing power. Rather, it consumes energy. Further, it undoes the work of photosynthesis. There is 25% loss of fixed CO₂. Therefore, photorespiration is a highly wasteful process. This happens only in case of C₃ plants.
