Classification of Algae

The classification of algae into taxonomic groups is based upon the  same rules that are used for the classification of land plants, but the  organization of groups of algae above the order level has changed  substantially since 1960. Research using electron microscopes has  demonstrated differences in features, such as the flagellar apparatus,  cell division process, and organelle structure and function, that are  important in the classification of algae. Similarities and differences  among algal, fungal, and protozoan groups have led scientists to propose  major taxonomic changes, and these changes are continuing.

Division-level  classification, as with kingdom-level classification, is tenuous for  algae. For example, some phycologists place the classes  Bacillariophyceae, Phaeophyceae, and Xanthophyceae in the division  Chromophyta, whereas others place each class in separate divisions:  Bacillariophyta, Phaeophyta, and Xanthophyta. Yet, almost all  phycologists agree on the definition of the respective classes  Bacillariophyceae, Phaeophyceae, and Xanthophyceae.

The classes are distinguished by the structure of  flagellate cells (e.g., scales, angle of flagellar insertion,  microtubular roots, and striated roots), the nuclear division process  (mitosis), the cytoplasmic division process (cytokinesis), and the cell  covering. Many scientists combine the Micromonadophyceae with the  Pleurastrophyceae, naming the combined group the Prasinophyceae.  “Phylum” and “division” represent the same level of  organization; the former is the zoological term, the latter is the  botanical term
