Light microscopy of a diatom alga. Diatoms are ubiquitous in fresh and sea water worldwide, as well as in damp soils and most other moist environments. They are a fundamental component of phytoplankton, producing organic compounds by photosynthesis, and form part of the base of the food chain. They are unique in having a capsule made of silica, called a frustule. Darkfield illumination. | |
