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 may be discoid, plate-like, 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.
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 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, green algae contain chlorophyll a and chlorophyll b and store food as starch in their plastids.
Lambia is a genus of green algae in the family Bryopsidaceae.
Acetabularia is a genus of green algae in the family Polyphysaceae, Typically found in subtropical waters, Acetabularia is a single-celled organism, but gigantic in size and complex in form, making it an excellent model organism for studying cell biology. In form, the mature Acetabularia resembles the round leaves of a nasturtium, is 4 to 10 cm tall and has three anatomical parts: a bottom rhizoid that resembles a set of short roots; a long stalk in the middle; and a top umbrella of branches that may fuse into a cap. Unlike other giant unicellular organisms, which are multinucleate, Acetabularia has a single nucleus, located in the rhizoid and allows the cell to regenerate completely if its cap is removed. The caps of two Acetabularia may also be exchanged, even from two different species. In addition, if a piece of the stem is removed, with no access to the nucleus in the rhizoid, this isolated stem piece will also grow a new cap.
Felix Eugen Fritsch FRS was a British biologist.
Fritschiella is a genus of green algae in the family Fritschiellaceae. There are two species F. tuberosa and a new freshwater species from China, F. aquatilis
Mychonastes is a genus of green algae, specifically of the Chlorophyceae.
Paulschulzia is a genus of green algae, specifically of the family Tetrasporaceae.
Pseudomuriella is a genus of green algae, specifically of the class Chlorophyceae.
Tellamia is a monotypic genus of green algae, in the family Kornmanniaceae. It has only one known species, Tellamia contortaBatters, 1895
Trebouxia is a unicellular green alga. It is a photosynthetic organism that can exist in almost all habitats found in polar, tropical, and temperate regions. It can either exist in a symbiotic relationship with fungi in the form of lichen or it can survive independently as a free-living organism alone or in colonies. Trebouxia is the most common photobiont in extant lichens. It is a primary producer of marine, freshwater and terrestrial ecosystems. It uses carotenoids and chlorophyll a and b to harvest energy from the sun and provide nutrients to various animals and insects.
Trentepohlia is a genus of filamentous chlorophyte green algae in the family Trentepohliaceae, living free on terrestrial supports such as tree trunks and wet rocks or symbiotically in lichens. The filaments of Trentepohlia have a strong orange colour caused by the presence of large quantities of carotenoid pigments which mask the green of the chlorophyll.
Groenbladia is a genus of green algae, specifically of the Desmidiaceae.
Heimansia is a genus of green algae, specifically of the Desmidiaceae.
Klebahniella is a genus of green algae in the family Chaetophoraceae.
Nayalia is a genus of green algae in the family Chaetophoraceae.
Zoddaea is a monotypic genus of green algae in the family Chaetophoraceae. It only contains one known species, Zoddaea viridisBorzì
Korshikoviella is a genus of green algae in the family Characiaceae.
Pediastrum duplex is a species of fresh water green algae in the genus Pediastrum.
