Resistances along the CO2 diffusion pathway inside leaves [PDF]

Journal of Experimental Botany, 2009
CO(2) faces a series of resistances while diffusing between the substomatal cavities and the sites of carboxylation within chloroplasts. The absence of techniques to measure the resistance of individual steps makes it difficult to define their relative importance.
