| Diatoms are microscopic unicellular algae which are important components of the phytoplankton throughout the world. Diatoms possess unique silica shells or frustules which are composed of biogenic silica. The majority of species float freely in the water column, but some attach to plants or sediment. The frustules are deposited on the bottom of streams, lakes, and oceans when the organisms die. | ||
