C3 plants have no mechanism to avoid photorespiration
C4 plants reduce photorespiration by separating the light reaction in the mesophyll cells from the light-
independent reaction in the bundle-sheath cells
CAM plants minimize photorespiration by collecting and storing CO2 at night and keeping their stomata
closed during the day
C4 plants include corn, sugarcane, and many grasses
CAM plants can undergo photophosphorylation in the absence of sunlight
