Sphaeropleales
Sphaeropleales is an order of green algae that used to be called Chlorococcales. The order includes some of the most common freshwater planktonic algae such as '' Scenedesmus'' and '' Pediastrum''. The Spaeropleales includes vegetatively non-motile unicellular or colonial taxa that have biflagellate zoospores with flagella that are directly opposed in direction (the DO arrangement): ''Sphaeroplea'', '' Atractomorpha'', ''Neochloris'', ''Hydrodictyon'', and '' Pediastrum''. All of these taxa have basal body core connections. With an increase in the number of taxa for which sequence data are available, there is evidence of an expanded DO clade that includes additional zoosporic ('' Bracteacoccus'', '' Schroederia'') and some strictly autosporic genera such as ''Ankistrodesmus'', '' Scenedesmus'', ''Selenastrum'', and ''Monoraphidium''.

Pediastrum Duplex
''Pediastrum duplex'' is a species of fresh water green algae in the genus '' Pediastrum''. They form nonmotile coenobia (colonies) with a fixed number of cells. These coenobia are flat and have a circular shape. The cell bodies are polygonal, are granulated and have horn-like projections. They reproduce these autocolonies asexually. The colonies usually contain 8 to 32 cells, with examples of 4, 64 or 128 occurring rarely.

Pediastrum
''Pediastrum'' is a genus of green algae, in the family Hydrodictyaceae. It is a photoautotrophic, nonmotile coenobial (fixed number of cells) green algae that inhabits freshwater environments. Morphology ''Pediastrum'' is a genus usually look like a green star in the pond or lake. They are coenobial green algae composed of 22 to 27 cells, which are orderly arranged in a circular, flat disk. The diameter of a single coenobium can range from 20 to 80 μm, so they belong to the group of microalgae. Cells in ''Pediastrum'' can be divided into interior cells and peripheral cells by position in the coenobium or their shapes. Some of the species have intracellular cell spaces between interior cells, while some would closely aggregate together. The peripheral cells surround outside the interior cells, and they usually possess bristles, V-liked cutting edges, or wavy projections. Phylogeny The genus of ''Pediastrum'' belongs to the Hydrodictyaceae family, along with '' Psuedopediast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scenedesmus
''Scenedesmus'' is a genus of green algae, in the class Chlorophyceae. They are colonial and non-motile. Taxonomy Currently, there are 74 taxonomically accepted species of ''Scenedesmus''. Additionally, several subgenera have been identified, but vary according to the source. Hegewald denotes ''Acutodesmus'', ''Desmodesmus'', and ''Scenedesmus'' as the three major categories. ''Acutodesmus'' is characterized as having acute cell poles, while ''Desmodesmus'' and ''Scenedesmus'' have obtuse/truncated cell poles (differentiated by the presence or absence of spines respectively). Fossil records date ''Scenedesmus'' from 70 to 100 million years ago with ''Desmodesmus'' suspected to be the youngest of these three groups. Basic biology ''Scenedesmus'' is one of the most common freshwater algae genera; however, the extremely diverse morphologies found within species make identification difficult.Lürling, Miquel.

Schroederiaceae
''Schroederia'' is a genus of green algae in the family Schroederiaceae. Schroederiaceae is a monotypic taxon; ''Schroederia'' is its only genus. The genus was circumscribed by Ernst Johann Lemmermann in Hedwigia vol.37 on page 311 in 1898. The genus name of ''Schroederia'' is in honour of Ludwig Julius Bruno Schröder (1867–1928), who was a German teacher, botanist (Algology and Bryology), also Hydrobiologist and Zoologist. He worked as a deputy head teacher in Breslau.
