C4 plants differ from C3 plants because C3 plants while C4 plants gain CO2 via photorespiration; lose CO2 via photorespiration have mesophyll cells that fix CO2 and contain the Calvin cycle; have mesophyll cells that fix CO2 and bundle sheath cells that contain the Calvin cycle concentrate CO2 near rubisco; cannot concentrate CO2 near rubisco can concentrate the CO2 by regulating the stomata closure; can concentrate CO2 at night produce a four-carbon intermediate after CO2 fixation; produce a three-carbon intermediate after CO2 fixation
