In four of the five species, in which stomatal conductance decreased with increasing CO 2, the cyclic CO 2 treatments reduced stomatal conductance. In those species, both photosynthesis and the photochemical …

Gas exchange is thus an essential process in energy metabolism, and gas exchange is an essential prerequisite to life, because where energy is lacking, life cannot continue. The basic mechanism of gas exchange is diffusion across a moist membrane.
