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] |
Haptophyceae
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 (biology), class Taxonomic rank, 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 algae, red algal endosymbionts. Haptophyte chloroplasts contain chlorophylls Chlorophyll a, a, Chlorophyll_c#Chlorophyll_c1, c1, and Chlorophyll_c#Chlorophyll_c2, c2 but lack chlorophyll Chlorophyll_b, b. For carotenoids, they have beta-carotene, beta-, Α-Carotene, alpha-, and γ-Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
