Previous versions of the Adl et al., 2019 classification appeared in Adl et al. 2005 and Adl et al. 2012, [18] [19] also in the chapter "Bacillariophyta" by Mann, Crawford & Round in the 2017 Handbook of the Protists edited by Archibald et al., [22] in which some groups later named as formal taxa are listed under informal names (leptocylindrids ...

Diatoms are eukaryotic organisms in the phylum Bacillariophyta. This page contains articles about diatoms and diatomists.. Older classifications used to subdivide diatoms into Centrales and Pennales (with Bacillariophyceae used as a class), whereas more recent ones use a three classes system: Bacillariophyceae, Coscinodiscophyceae and Fragilariophyceae.
The Coscinodiscophyceae are a class(s) of diatoms. [1] They are similar to the Centrales, a traditional, paraphyletic subdivision of the heterokont algae known as diatoms. [2] [3] [4] The order is named for the shape of the cell walls (or valves or frustules) of centric diatoms, which are circular or ellipsoid in valve view.
The native range of Thalassiosira weissflogii is unclear, but it is found in marine, brackish and freshwater environments. It seems to grow best at higher salinities [6] and occurs in coastal waters in the Atlantic and Pacific Oceans and in rivers and lakes in Europe, Asia, South and North America, including the Great Lakes, where it was thought to have been introduced in ballast water.

Auxospores are involved in re-establishing the normal size in diatoms, as successive mitotic cell divisions leads to a decrease in cell size. This occurs because each daughter cell produced by cell division inherits one of the two valves that make up the frustule (a silica cell wall), and then grows a smaller valve within it.
