C3 Plant

C3 plants use the enzyme rubisco to catalyze the carbon fixation of CO2 and RuBP to make a three carbon compound called phosphoglycerate before going on into the Calvin Cycle.  These plants use CO2 from the air and need to keep their stomata open to allow gas exchange. This however leads to extreme water loss. Due to this, C3 plants can not thrive in extremely hot or arid climates.  They need an abundant amount of ground water and CO2 as well as moderate temperatures to successfully carry out this process. The picture shows a C3 plant called barley. Some examples of C3 plants are (Korean?) barley, rice, and other grains.
