If the stomata do not open, it will limit the amount of CO2 that can enter the plant for photosynthesis. This will result in a buildup of oxygen and a decrease in the ratio of CO2 to oxygen, making photorespiration (a process where oxygen is used instead of CO2 by the enzyme RuBisCO) more favorable.
