Caption: False colour scanning electron micrograph of a fractured turnip leaf, Brassica rapa, showing the mesophyll layers; the palisade mesophyll (top) & the spongy mesophyll (bottom). Palisade cells, in tightly packed rows, contain chloroplasts, where the light reactions of photosynthesis take place to produce sugar for the plant. Below, in the spongy mesophyll, the cells are loosely packed with large air spaces & few chloroplasts. This layer is involved in the circulation of gases exchanged with the environment through pores (stomata) in the epidermis. The lower epidermis, in contact with the spongy mesophyll, has more stomata than the upper. Magnification: X700 at
