WebChromista. Chromista is a proposed but seemingly polyphyletic [1] [2] biological kingdom consisting of single-celled and multicellular eukaryotic species that share similar features in their photosynthetic organelles ( plastids ). [3] It includes all protists whose plastids contain chlorophyll c, such as some algae, diatoms, oomycetes, and ...

Golden algae - Wikipedia
WebApr 8, 2024 · Chrysophyceae is a family of algae distinguished primarily by their flagellar structure (although there are also species that are non-motile). The majority of them have two flagella. One of them is active and possesses mastigonemes. It accounts for forward motion. The other flagellum is smooth and uninteresting. 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 the … 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.

Phylogenetic and functional diversity of Chrysophyceae in
WebChrysophytes (Chrysophyceae, Heterokontophyta) are mainly unicellular or colonial golden-brown algae, which may be flagellate, but there are also some multicellular species (van den Hoek et al., 1995). This class contains about 200 genera and 1000 species, and most of them are found in fresh waters. WebChrysophyte algae (class Chrysophyceae) represent an extensive but rather poorly studied group of algae with underestimated diversity, a complex evolutionary history, and many unresolved problems in their phylogeny [28,29,30]. The study of the diversity and taxonomy of chrysophytes is complicated by the fact that they are hard-to-cultivate ... WebChrysophyceae.
