Prymnesium Chiton
''Prymnesium'' is a genus of haptophytes, including the species '' Prymnesium parvum''. The genus is a unicellular motile alga. It is ellipsoidal in shape one flagellum is straight and there are two longer ones which enable movement. The name Latinizes the Greek ' ‘cable (for mooring)’, from ' ‘stern’, from ' ‘hindmost’. ''Prymnesium'' was likely first recognized and drawn (although not named as such) on July 1, 1920, and then (seemingly independently) officially named shortly afterwards on July 6, 1920. Morphology Species The taxonomy of Prymnesiales was revised in 2011. With this revision, ten additional species were added to the genus, namely '' P. neolepis'' (previously assigned to '' Hyalolithus''), '' P. palpebrale'', '' P. polylepis'', '' P. kappa'', '' P. chiton'', '' P. minus'' (previously assigned to '' Chrysochromulina''), '' P. neustophilum'', '' P. pienaarii'', '' P. pigrum'', and '' P. simplex'' (previously assigned to '' Platychrysis''). * '' ...

Emendation (zoology)
In zoological nomenclature, emendations are intentional alterations made to the spelling of taxon names. In bacteriological nomenclature, emendations are made to the circumscription of a taxon. All emendations are considered by default to be available names. An emendation may be "justified" (when the original spelling is demonstrably incorrect under the International Code of Zoological Nomenclature,International Commission on Zoological Nomenclature. 1999International Code of Zoological Nomenclature. 4th ed.London: The International Trust for Zoological Nomenclature. Article 32.5), or it may be "unjustified" (if the change violates the rules of the Code). A justified emendation is different from a " mandatory change" only in that the latter is required by the Code, under Article 34. An unjustified emendation is different from an " incorrect subsequent spelling" in that the latter is an unintentional change, while an emendation is explicitly intentional, and in that an incorrect ...

Prymnesium Polylepis
''Prymnesium'' is a genus of haptophytes, including the species '' Prymnesium parvum''. The genus is a unicellular motile alga.

Chrysochromulina
''Chrysochromulina'' is a genus of haptophytes. This phytoplankton is distributed globally in brackish and marine waters across approximately 60 known species. All ''Chrysochromulina'' species are phototrophic, however some have been shown to be mixotrophic, including exhibiting phagotrophy under certain environmental conditions. The cells are small, characterized by having scales, and typically observed using electron microscopy. Some species, under certain environmental conditions have been shown to produce toxic compounds that are harmful to larger marine life including fish. Morphology Individuals of the genus are known to grow between 3.0 and 13.0 μm in length, with the largest being those of the '' Chrysochromulina polylepis'' species. The cell surface is covered with plate-like scales, with additional layers of different scale types often overlaid. As is characteristic of all haptophytes, members of the genus ''Chrysochromulina'' possess two flagella and a uniqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prymnesium Minus
''Prymnesium'' is a genus of haptophytes, including the species '' Prymnesium parvum''. The genus is a unicellular motile alga. It is ellipsoidal in shape one flagellum is straight and there are two longer ones which enable movement. The name Latinizes the Greek ' ‘cable (for mooring)’, from ' ‘stern’, from ' ‘hindmost’. ''Prymnesium'' was likely first recognized and drawn (although not named as such) on July 1, 1920, and then (seemingly independently) officially named shortly afterwards on July 6, 1920. Morphology Species The taxonomy of Prymnesiales was revised in 2011. With this revision, ten additional species were added to the genus, namely '' P. neolepis'' (previously assigned to '' Hyalolithus''), '' P. palpebrale'', '' P. polylepis'', '' P. kappa'', '' P. chiton'', '' P. minus'' (previously assigned to '' Chrysochromulina''), '' P. neustophilum'', '' P. pienaarii'', '' P. pigrum'', and '' P. simplex'' (previously assigned to '' Platychrysis''). * '' ...

Prymnesium Palpebrale
''Prymnesium'' is a genus of haptophytes, including the species ''Prymnesium parvum''. The genus is a unicellular motile alga. It is ellipsoidal in shape one flagellum is straight and there are two longer ones which enable movement. The name Latinizes the Greek ' ‘cable (for mooring (watercraft), mooring)’, from ' ‘stern’, from ' ‘hindmost’. ''Prymnesium'' was likely first recognized and drawn (although not named as such) on July 1, 1920, and then (seemingly independently) officially named shortly afterwards on July 6, 1920.

Haptophyte
The haptophytes, classified either as the Haptophyta, Haptophytina or Prymnesiophyta (named for '' Prymnesium''), are a clade of algae. The names Haptophyceae or Prymnesiophyceae are sometimes used instead. This ending implies classification at the class rank rather than as a division. Although the phylogenetics of this group has become much better understood in recent years, there remains some dispute over which rank is most appropriate. Characteristics The chloroplasts are pigmented similarly to those of the heterokonts, but the structure of the rest of the cell is different, so it may be that they are a separate line whose chloroplasts are derived from similar red algal endosymbionts. Haptophyte chloroplasts contain chlorophylls a, c1, and c2 but lack chlorophyll b. For carotenoids, they have beta-, alpha-, and gamma- carotenes. Like diatoms and brown algae, they have also fucoxanthin, an oxidized isoprenoid derivative that is likely the most important driver of t ...
