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 ...

Three diatom species were sent to the International Space Station, together with the huge (6 mm length) diatoms of Antarctica and the exclusive colonial diatom, Bacillaria paradoxa.
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.
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.
Scanning electron micrographs of frustules from some algae species - scale bar = 10 micrometres in a,c and d and 20 micrometres in b. A frustule is the hard and porous cell wall or external layer of diatoms.
