Cryptaulax (cryptomonad)
''Cryptaulax'' was introduced by Skuja (Skuja, 1948). He considered it to be a type of cryptomonad. Subsequent studies suggest that it is euglenozoan. Because Skuja had clearly misidentified the flagellate as a cryptomonad, Vørs argued that at least some species should be placed in the genus ''Rhynchobodo''. This thinking was not adopted by Simpson. The genus had been erected by Skuja to accommodate ''Spiromonas akopus'', described by him in 1939.Skuja, H. 1939. Beitrage zur Algenflora Lettlands, 2. Acta Horti. Bot. Univ. Latviensis 11/12 The genus name ''Spiromonas'' had previously been applied to other organisms. This invalidates the name according to the rules of nomenclature, and requires a replacement name - hence ''Cryptaulax''. The similarity of the general morphology of ''C. akopus'' with other species that have been studied in more detail and deemed to be euglenozoan support the argument that the genus is euglenozoan. Species ''Cryptaulax akopos'' – ''Crypt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eukaryota
Eukaryotes () are organisms whose cells have a nucleus. All animals, plants, fungi, and many unicellular organisms, are Eukaryotes. They belong to the group of organisms Eukaryota or Eukarya, which is one of the three domains of life. Bacteria and Archaea (both prokaryotes) make up the other two domains. The eukaryotes are usually now regarded as having emerged in the Archaea or as a sister of the Asgard archaea. This implies that there are only two domains of life, Bacteria and Archaea, with eukaryotes incorporated among archaea. Eukaryotes represent a small minority of the number of organisms, but, due to their generally much larger size, their collective global biomass is estimated to be about equal to that of prokaryotes. Eukaryotes emerged approximately 2.3–1.8 billion years ago, during the Proterozoic eon, likely as Flagellated cell, flagellated phagotrophs. Their name comes from the Greek language, Greek wikt:εὖ, εὖ (''eu'', "well" or "good") and wikt:� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cryptomonad
The cryptomonads (or cryptophytes) are a group of algae, most of which have plastids. They are common in freshwater, and also occur in marine and brackish habitats. Each cell is around 10–50 μm in size and flattened in shape, with an anterior groove or pocket. At the edge of the pocket there are typically two slightly unequal flagella. Some may exhibit mixotrophy. Characteristics Cryptomonads are distinguished by the presence of characteristic extrusomes called ejectosomes, which consist of two connected spiral ribbons held under tension. If the cells are irritated either by mechanical, chemical or light stress, they discharge, propelling the cell in a zig-zag course away from the disturbance. Large ejectosomes, visible under the light microscope, are associated with the pocket; smaller ones occur underneath the periplast, the cryptophyte-specific cell surrounding. Except for the class '' Goniomonadea'', which lacks plastids entirely, and ''Cryptomonas paramecium'' ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
