Chrysophyte, single-celled, naked; with two unequal flagella; cells spherical, cylindrical to pyriform, sometimes metabolic, usually free-swimming but occasionally attaching to surfaces with posterior end, or becoming rhizopodial or palmelloid; small and loose colonial aggregations of flagellated cells also occurring in a few species; cells with 1-2 (rarely more) chloroplasts, with or without an eyespot and/or pyrenoid; swelling at proximal end of short flagellum overlying eyespot known for some species; chloroplasts sometimes much reduced and pale or completely lost after abnormal division; contractile vacuoles 1-4; chrysolaminaran vacuole usually large, posterior; many species with peripheral extrusomes (mucocysts, discobolocysts); nutrition phototrophic, mixotrophic and heterotrophic; asexual reproduction by cell division in motile or palmelloid state; stomatocysts of various forms known from several species; many species in freshwater, some in brackish and marine waters and on soil; some species (especially Ochromonas danica) are important in physiological and molecular studies.
