CIL:39035 - http://www.cellimagelibrary.org/images/39035
Description: A Nomarski differential interference microscopy image illustrating the frustule (silica cell wall) of a marine centric, Aulacodiscus formosus diatom (unicellular alga). Diatoms are photosynthesising algae that live in most aquatic environments, both fresh and salt water. They are non-motile and are restricted to shallow waters as they require sunlight for photosynthesis. A centric diatom is one that displays radial symmetry. More diatom images are available as CIL:39032-39034.
