The heterokonts or stramenopiles are a major line of eukaryotes. Most are algae, ranging from the giant multicellular kelp to the unicellular diatoms, which are a primary component of plankton. However some are colorless, most notably the parasitic water moulds, which superficially resemble fungi. The exact circumscription and treatment of the group varies considerably.
