WEBJan 21, 2018 · Diatoms are a common type of unicellular phytoplankton that likely originated around the Jurassic period. Diatoms can form colonies characterized by particular shapes (e.g., stars, fans, and ribbons) and are encapsulated by a unique cell wall composed of silica, termed a frustule.
4.4: Diatoms - Biology LibreTexts
WEBWe are still trying to figure out how to determine what a diatom "species" is and, so far, they have been classified based on the morphology of their frustules. Using this classification, historically there were two major groups of diatoms: centric (have radial symmetry) and pennate (have bilateral symmetry).
