However, more atmospheric CO2 is predicted to increase crop biomass and subsequent yields, and reduce water use by allowing
plant stomates to open over shorter periods, thus assimilating the same amount of atmospheric CO2 while conserving moisture (Cutforth et al. 2007).

CAM
plants are unique in that under drought conditions their
stomates (leaf pores) are open at night rather than during the day (as is the case with most
plants).
Plants respond to differences in how much CO2 is in the air by varying the frequency (number per unit area) of the pores on the leaf surface (called
stomates).
When
plant water status drops below minimum levels required for cell functioning,
stomates quickly close and carbon fixation thus stops.
