Epithemia diatom. Polarised light micrograph of a Epithemia sp. diatom on an aquatic plant. Diatoms are single-celled photosynthetic algae, of which there are about 100,000 species. They have mineralised cell walls (frustules) that contain silica and provide protection and support. They form an important part of the plankton at the base of the marine and freshwater food chains.
