mesophyll - Internal tissue of leaf-blade differentiated into palisade and spongy mesophyll. In dorsi-ventral leaves palisade mesophyll consists of elongated cells immediately below upper epidermis with their long axes at right-angles to leaf surface; these cells contain numerous chloroplasts and are chiefly concerned in photosynthesis. Spongy mesophyll is a tissue of irregular, loosely arranged cells, containing fewer chloroplasts, with large air spaces between the cells, communicating through stomata with atmosphere outside.
