The heterokonts or stramenopiles are a major line of eukaryotes with more than 100,000 known species,[1] most of them diatoms.[2]
Heterokonts are mostly algae. In one stage of their life cycle they have two unequal flagella. They include both single-celled types and brown algae (seaweeds such as kelp and Sargassum). They are members of the Kingdom Chromalveolata.
