Light micrograph of diatoms,Campylodiscus Sp. Diatoms are a distinctive group of single-celled algae containing about 10,000 species. They form a large part of the plankton at the base of the marine & freshwater food chains. A characteristic feature of diatoms is their intricately patterned,silica-impregnated glass-like cell wall,or frustule. The frustule consists of 2 halves which fit together like the lid and bottom of a box. The frustule is often decorated with rows of tiny holes,known as striae,which are arranged radially in centric diatoms and on the 2 sides of a central axis in pennate diatoms.
