It includes all eukaryotes whose plastids contain chlorophyll c and are surrounded by four membranes.
Introduction to the Chromista. From microbes to giants. . . It may seem hard to believe that microscopic diatoms, with their delicate silica skeletons only forty millionths of a meter long, can be related to the giant kelps, which may grow as long as fifty meters, or that either one is related to the downy mildew that nearly destroyed the French wine industry.
The British protozoologist Thomas Cavalier-Smith, since 1998, developed a six-kingdom model: Bacteria, Animalia, Plantae, Fungi, Protozoa and Chromista. In his context, paraphyletic groups take preference over clades: both protist kingdoms Protozoa and Chromista contain paraphyletic phyla such as Apusozoa, Eolouka or Opisthosporidia.

The Phaeophyta, for example, are primarily known for their large marine kelps, but the group also includes microscopic freshwater species. Likewise the diatoms have many marine and freshwater ...
