(b) Response to high light intensities

(c) Greater productivity of biomass

(d) Photorespiration

This question was addressed to me by my college professor while I was bunking the class.

I'm obligated to ask this question of Higher Plants Photosynthesis topic in section Photosynthesis in Higher Plants of Biology – Class 11

Answer 1

Correct answer is (d) Photorespiration

Best explanation: C4 plants show some special adaptations to survive extreme climate, such as tolerance of higher temperatures, response to high intensity lights, lack of photorespiration and greater productivity of biomass.
