Chlorococcales
Chlorococcales is a formerly recognized order of green algae in the class Chlorophyceae. , the type family Chlorococcaceae was placed in the order Chlamydomonadales. Conventionally, many groups of coccoid green algae were lumped in the order Chlorococcales sensu lato by Komárek & Fott (1983), based on Pascher's (1918) idea of establishing orders according to life forms. However, coccoid green algae are currently placed in several orders of Chlorophyceae, Trebouxiophyceae, Ulvophyceae (e.g., '' Chlorocystis'') and Prasinophyceae within the division Chlorophyta, or in the division Charophyta (e.g., Chlorokybales, Desmidiales). Families According to Komárek & Fott (1983): * Chlorococcaceae ( Chlorococcoideae, Spongiococcoideae) * Palmellaceae ( Hormotiloideae, Palmelloideae, Neochloridoideae, Chlorosarcinoideae) * Chlorochytriaceae * Dicranochaetaceae * Characiaceae ( Fernandinelloideae, Characioideae, Schroederioideae) * Treubariaceae * Golenkiniaceae * Hydrodict ...

Chlorophyta
Chlorophyta or Prasinophyta is a taxon of green algae informally called chlorophytes. The name is used in two very different senses, so care is needed to determine the use by a particular author. In older classification systems, it refers to a highly paraphyletic group of ''all'' the green algae within the green plants (Viridiplantae) and thus includes about 7,000 species of mostly aquatic photosynthetic eukaryotic organisms. In newer classifications, it refers to the sister clade of the streptophytes/ charophytes. The clade Streptophyta consists of the Charophyta in which the Embryophyta (land plants) emerged. In this latter sense the Chlorophyta includes only about 4,300 species. About 90% of all known species live in freshwater. Like the land plants ( embryophytes: bryophytes and tracheophytes), green algae (chlorophytes and charophytes besides embryophytes) contain chlorophyll a and chlorophyll b and store food as starch in their plastids.

Chlorophyceae
The Chlorophyceae are one of the classes of green algae, distinguished mainly on the basis of ultrastructural morphology. They are usually green due to the dominance of pigments chlorophyll a and chlorophyll b. The chloroplast A chloroplast () is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells. The photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it ... may be wikt:discoid, discoid, plate-like, wikt:reticulate, reticulate, cup-shaped, spiral or ribbon shaped in different species. Most of the members have one or more storage bodies called pyrenoids located in the chloroplast. Pyrenoids contain protein besides starch. Some green algae may store food in the form of oil droplets. They usually have a cell wall made up of an inner layer of cellulose and outer layer of pectose. General characteristics * the body may be unicellular, colonial, filamentous or mult ...

Order (biology)
Order ( la, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Golenkiniaceae
''Golenkinia'' is a genus of green algae first described in 1894 by Robert Chodat. The genus is named for the Russian phycologist Mikhail Iljitsch Golenkin. ''Golenkinia'' species live in fresh water (including bodies of black water such as Winyah Bay) and are found around the world. Description Members of ''Golenkinia'' are spherical unicellular organisms with numerous radiating spines. Their cell walls are notably thick, which distinguishes them from members of the genus '' Golenkinopsis''. They contain a single walled cup-shaped chloroplast, which in turn contains a pyrenoid in its base. The pyrenoid is typically sheathed in starch. Species of ''Golenkinia'' are typically solitary and do not form colonies or coenobia except under laboratory conditions. Their slender spines may become entangled, creating the false impression that the algae have formed a colony. Taxonomic status The precise taxonomic status of ''Golenkinia'' is somewhat unclear due to the large number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
