Light micrograph of the diatom Triceratium sp. The diatoms are a distinctive group of single-celled algae containing about 10,000 species. They form an important part of the plankton at the base of the marine & freshwater food chains. The characteristic feature of diatoms is their intricately patterned,glass- like cell wall,or frustule. The frustule consists of 2 halves which fit together like the lid & bottom of a box. It is often decorated with rows of tiny holes,known as striae,which are arranged either radially (as here) or on the 2 sides of a central axis. Magnification unknown | |
