Light micrograph of the diatom Fragillaria sp.. The rectangular objects seen here are simple colonies of Fragillaria. They consist of a stack of diatoms which have failed to separate following cell division,each glued to its neighbours by a mucilaginous material. Diatoms are a group of single-celled algae distinguished by their intricately-patterned glass-like cell wall or "frustule". The frustule consists of two halves,the valves,which fit together like the lid and bottom of a box. Diatoms form an important component of the marine & freshwater plankton.
