The modern usage of the name 'Chlorophyta' was established in 2004, when phycologists Lewis & McCourt firmly separated the chlorophytes from the streptophytes on the basis of molecular phylogenetics. All green algae that were more closely related to land plants than to chlorophytes were grouped as a paraphyletic division Charophyta. [46]
The green algae (sg.: green alga) are a group of chlorophyll-containing autotrophic eukaryotes consisting of the phylum Prasinodermophyta and its unnamed sister group that contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep within the charophytes as a sister of the Zygnematophyceae.
Green algae, Scenedesmus Green algae, Crucigenia. Scenedesmaceae is a family of green algae in the order Sphaeropleales. Scenedesmus algae are commonly found in freshwater plankton. The former family Coelastraceae is considered a synonym of Scenedesmaceae. [1]
The Chlorophyceae are one of the classes of green algae, distinguished mainly on the basis of ultrastructural morphology. [2] 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.
Despite this, the families and genera are still in use, because the differences have not been reconciled into a single, useful classification system. [4] In 2008, Nakada et al. defined a number of well-supported clades within Chlamydomonadales using PhyloCode. Their relationships, as well as a few representative genera and species, are shown ...
Chlorella sorokiniana is a species of freshwater green microalga in the Division Chlorophyta. [2] It has a characteristic emerald-green color and pleasant grass odor. Its cells divide rapidly to produce four new cells every 17 to 24 hours. The alga was described by Martinus W. Beijerinck in 1890. [3]
Chlorella is a genus of about thirteen species of single-celled green algae of the division Chlorophyta. The cells are spherical in shape, about 2 to 10 μm in diameter, and are without flagella. Their chloroplasts contain the green photosynthetic pigments chlorophyll-a and -b.
The Oedogoniales are an order of filamentous freshwater green algae of the class Chlorophyceae. [1] The order is well-defined and has several unique features, including asexual reproduction with zoospores that possess stephanokont flagella: numerous short flagella arranged in a subapical whorl. [1]
