Nephroselmis
''Nephroselmis'' is a genus of green algae. It has been placed in the family Nephroselmidaceae, although a 2009 study suggests that it should be separated into its own class, Nephroselmidophyceae. One species can be an endosymbiont of ''Hatena arenicola''. Morphology The cell body is right-left flattened. On the ventral side are two heterodynamic unequal flagella, the shorter beats towards the anterior direction while the long trails behind. ''Nephroselmis'' have a single cup-shaped chloroplast that contains an eyespot in its anterior-ventral edge below the short flagellum and a pyrenoid with starch plates. Vacuole is located in the left-anterior side, nucleus is located in the right-posterior side. The flagellar root system consists of a rhizoplast and three microtubular roots, one of which is multilayered. All the cells surface area is covered with layers of unminerallized scales, while the surface of the flagella has hairs as well. The cell body surface is covered by two to ...

Hatena Arenicola
''Hatena arenicola'' is a species of single-celled eukaryotes discovered in 2000, and first reported in 2005. It was discovered by Japanese biologists Noriko Okamoto and Isao Inouye at the University of Tsukuba, and they gave the scientific description and formal name in 2006. The species is a flagellate, and can resemble a plant at one stage of its life, in which it carries a photosynthesizing alga inside itself, or an animal, acting as predator in another stage of its life. Researchers believe that this organism is in the process of secondary endosymbiosis, in which one organism is incorporated into another, resulting in a completely new life form. Discovery ''H. arenicola'' was first noticed as algal bloom in 2000 from Isonoura beach in Japan. It was found in the area of moderately sheltered sandy shore, where a number of algae surfaced during tsunami. The specimens were present in the upper edge of the seepage face. It can be found throughout the year, except in winter. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Green Algae
The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep in the Charophyte alga as sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to properly include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. A few other organi ...
