WebA more recent classification divides the diatoms into three classes or subclasses and a number of orders: It is probable there will be further revisions as understanding of their relationships increases. Diatoms generally range in size from ca. 2-200μm, and are composed of a cell wall composed primarily of silica. For many years the diatoms—treated either as a class (Bacillariophyceae) or a phylum (Bacillariophyta)—were divided into just 2 orders, corresponding to the centric and the pennate diatoms (Centrales and Pennales; alternative names Biddulphiales and Bacillariales, as used e.g. in Lee, 1989). This classification was extensively overhauled by Round, Crawford and Mann in 1990 who treat…
