Caption: Rosemary leaf cross section (Rosmarinus officinalis), animated coloured scanning electron micrograph (SEM). A thin waxy cuticle is present on the upper and lower surface of the leaf. The rectangular line of cells near top of the leaf (right below the cuticle) is the leaf epidermis containing epidermal cells (without chloroplasts). The cuticle and epidermis helps to protect the leaf. The leaf interior contains mesophyll parenchyma cells that consist of two types 1) palisade mesophyll, oblong cells near the upper epidermis arranged perpendicular to the epidermal cells and 2) spongy mesophyll, (not visible in this image). The packed palisade mesophyll cells contain chloroplasts that are the major leaf sites for photosynthesis. The spongy mesophyll cells are loosely packed, with few chloroplasts and are more involved with gas exchange.
