Question: Both C4 and CAM plants employ physiological and biochemical strategies to reduce photorespiration. Which of the following is an accurate comparison of the two strategies?
 A. C4 plants fix CO2 as the 4-carbon acid oxaloacetate, while CAM plants fix CO2 as the 5-carbon acid ribulose 1, 5-bisphosphate.
 B. C4 plants fix CO2 in the mesophyll but carry out the Calvin cycle in the bundle sheath, while CAM plants fix CO2 and carry out the Calvin cycle in the mesophyll.
