WebChrysophytes (Chrysophyceae, Heterokontophyta) are mainly unicellular or colonial golden-brown algae, which may be flagellate, but there are also some multicellular … WebChrysophyceae. Unicellular or colonial, often flagellate or with flagellate stages. A few are multicellular. Typically freshwater, sometimes in brackish or marine waters. Flagella are apical, unequal in length, and one has mastigonemes. Heterokont-type photoreceptor, with swelling at base of smooth flagellum, and eyespot within chloroplast.

The Chrysophyceae, usually called chrysophytes, chrysomonads, golden-brown algae or golden algae are a large group of algae, found mostly in freshwater. Golden algae is also commonly used to refer to a single species, Prymnesium parvum, which causes fish kills. The Chrysophyceae should not be confused with … See more Originally they were taken to include all such forms of the diatoms and multicellular brown algae, but since then they have been divided into several different groups (e.g., Haptophyceae, Synurophyceae) based on … See more Chrysophytes live mostly in freshwater, and are important for studies of food web dynamics in oligotrophic freshwater ecosystems, and for assessment of environmental degradation resulting from eutrophication and acid rain. See more Chrysophytes contain the pigment fucoxanthin. Because of this, they were once considered to be a specialized form of cyanobacteria. Because many of these organisms had a … See more The "primary" cell of chrysophytes contains two specialized flagella. The active, "feathered" (with mastigonemes) flagellum is oriented toward the moving direction. The smooth passive flagellum, oriented toward the opposite direction, may be present … See more Pascher (1914) Classification of the class Chrysophyceae according to Pascher (1914): • Division Chrysophyta Smith (1938) According to Smith (1938): • Class … See more • Andersen, R.
