WebHowever, both S L (11.2-34.2%) and MC L (4.8-26.4%) predominantly limited photosynthesis under relatively severe conditions, suggesting that stomatal closure was the main limitation and that the decline in mesophyll conductance was not negligible under strong environmental stress, even under well-watered greenhouse conditions. WebMesophyll cells are a type of ground tissue found in the plant's leaves. There are two types of mesophyll cells: Palisade mesophyll cells and spongey mesophyll cells. The most important role of the mesophyll cells is in photosynthesis. Mesophyll cells are large spaces within the leaf that allow carbon dioxide to move freely [1] [2]. References:

Web1 sep. 2012 · The mesophyll pathway comprises a series of ‘physical barriers’ to CO 2 diffusion, including air, cell walls, lipid membranes and liquid cytoplasm and stroma. The ‘physical barriers’ differ in nature and size (i.e. ‘distance’) among leaves, and thus there is a large variation among leaves in diffusion conductance to CO 2 in the mesophyll ( gm ).
