C3 plants: - co2 fixed to rubp by rubp carboxylase- forms 3-phosphoglycerate- chloroplasts in mesophyll cells- undergo photorespiration - best adapted to temperatures under 25 c and high moisturec4 plants:- co2 fixed to pep by pepcase- forms oxaloacetate- chloroplasts in mesophyll and bundle sheath cells- best adapted to high light intensity, high temperature, and limited rainfallcam plants: - night: co2 fixed to pep; forms c4 molecules- day: c4 molecules release co2 to calvin cycle- best adapted to extreme aridity
