Refer to the table below, created by a student to help learn the similarities and differences between C4 and CAM plants. Which statement best evaluates the accuracy of the student's table?

A) It is accurate as written. B) The two plant types do not use the same enzyme for initial carbon fixation. C) CAM plants use the same pattern of carbon fixation in mesophyll with transport to bundle sheath cells that C4 plants use. D) Only CAM plants restrict carbon fixation to nighttime, since C4 plants are able to fix carbon both at night and during the day when they carry out Calvin cycle reactions. E) Only C4 plants use energy to carry out the initial carbon-fixation process. A) It is accurate as written. B) The two plant types do not use the same enzyme for initial carbon fixation.
