Caption: Diatom alga. Scanning electron micrograph of a large marine diatom, Thalassiosira eccentrica, showing the entire cell. Diatoms are single-celled algae which produce an intricately patterned, glass-like cell wall, or frustule. The frustule consists of two halves which fit together like the lid and bottom of a box. It is often decorated with rows of tiny holes, known as striae. There are about 10, 000 species of diatom algae in freshwater and marine habitats. Diatoms produce food from sunlight by photosynthesis. As plankton, they form a major part of the food chain. Magnification: x325 at 35mm size. Magnification: x2800 at 8x10 inch size.
