The cellular organization of the mesophyll of leaf blades of coastal-aquatic plants is considered on the example of nine species from the families Juncaceae , Cyperaceae , Poaceae and Typhaceae . It is shown that the basis of the assimilative tissue of the above-water leaves in most plant species is the palisade parenchyma, represented by cells of different spatial configurations. Columnar cells of cylindrical shape with round or slightly oval bases are characteristic for plants of the families Juncaceae , Cyperaceae , Typhaceae , in the representatives of the Poaceae family, the palisade tissue is formed both by cells of simple and complex cellular contours. In this case, common features are found in the three-dimensional structure of the complicated forms of cells of the inner layers of the mesophyll in species from the families Poaceae , Cyperaceae , and Juncaceae .
