Diatom and green algae. Polarised light micrograph of a Navicula sp. diatom (top centre) over Draparnaldia sp. green algae bottom). 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. Magnification: x400, when printed 10 centimetres wide.
