Which Types of Plants Undergo the Most Photorespiration

Question

Which types of plants undergo the most photorespiration?
A) C₂ plants
B) C₃ plants
C) C₄ plants
D) CAM plants

Accepted Answer

C₃ plants are more susceptible to photorespiration because they use Rubisco to fix CO₂, which can also bind with O₂ to begin the photorespiration process. C₄ and CAM plants have adaptations that reduce photorespiration.
