Pyrrophyta. Approximately 2000 species of Pyrrophyta (from the Greek pyrrhos, meaning flames, and phyton, meaning plant) are known at present. Pyrrophyta have been identified in fossil deposits around the globe, from arctic to tropical seas, as well as in hypersaline waters, freshwater, and river deltas.
Fire algae are unicellular algae commonly found in oceans and in some fresh water sources that use flagella for motion. They are separated into two classes: dinoflagellates and cryptomonads. Dinoflagellates can cause a phenomenon known as a red tide, in which the ocean appears red due to their large abundance. Like some fungi, some species of Pyrrophyta are bioluminescent.
Pyrrophyta Two classes are recognized in the phylum Pyrrophyta: Dinophyceae (dinoflagellates) and Cryptophyceae (cryptomonads). Because all are unicellular, they are classified in the kingdom Protista. There are approximately one thousand mostly marine, mostly motile species.Pyrrophyta definition is - a division or other category of algae comprising yellowish-green to golden-brown algae that are mostly unicellular and biflagellate, that form starch, starchy compounds, or oil as food reserves, and that include the dinoflagellates and cryptomonads.Dinoflagellate evolution has been summarized into five principal organizational types: prorocentroid, dinophysoid, gonyaulacoid, peridinioid, and gymnodinoid. The transitions of marine species into fresh water have been infrequent events during the diversification of dinoflagellates and in most cases have not occurred recently, possibly as late as the Cretaceous.
Pyrrophyta a phylum of lower plants (algae). The plants are microscopic and usually mobile (with two or, less frequently, one flagellum in one or two intersecting grooves). They may be unicellular, colonial, or less frequently, filamentous. The majority are either naked or have a casing in the form of a carapace of two halves, formed of angular plates.Read More
