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.
