Leaf pores. Coloured environmental scanning electron micrograph (ESEM) of the surface of an unidentified leaf showing its partially-open pores (stomata). Gaseous exchange for photosynthesis occurs through the stomata when they are open. Unlike a conventional scanning electron microscope (SEM),samples placed into an environmental SEM do not need to be desiccated or coated in gold. Magnification unknown | |
