Pelagophyceae

	Pelagophyceae Pelagophycidae is a subclass (biology), class of heterokont algae.It is the sister group of the axodines. Together, they form the class Dictyochophyceae. All known species are marine. They can be single-celled (Coccus, coccoid or flagellate), palmelloid or filamentous. Some members (''Pelagomonas'') belong to picoplankton, and some other (''Sarcinochrysis'') are macroscopic attached organisms. The subclass contains 13 genera, 3 families and 2 orders (2017): * Order Pelagomonadales Andersen & Saunders 1993 Family Pelagomonadaceae Andersen & Saunders 1993 * genus ''Ankylochrysis'' Billard 1995 * genus ''Aureococcus'' Hargraves & Sieburth 1988 * genus ''Chrysophaeum'' Lewis & Bryan 1941 non Taylor 1951 * genus ''Pelagococcus'' Norris 1977 * genus ''Pelagomonas'' Andersen & Saunders 1993 * Order Sarcinochrysidales Gayral & Billard 1977 Family Chrysocystaceae Melkonian, Yoon & Andersen 2018 * genus ''Chrysocystis'' Lobban, Honda & Chihara 1995 * genus ''Chrysoreinh ...

	Pelagomonas ''Pelagomonas'' is a genus of heterokont algae. It is a monotypic genus and includes a single species, ''Pelagomonas calceolata'' which is a unicellular flagellate organism, an ubiquitous constituent of marine picoplankton. It is an ultra-planktonic marine alga. Description ''Pelagomonas calceolata'' is flagellum, uniflagellate, about 1.5 × 3 micrometre, μm in size. Microtubular roots, striated roots and a second basal body are absent. A thin organic theca surrounds most of the cell. There is a single chloroplast with a girdle Lamella (cell biology), lamella and a single, dense mitochondrion with tubular cristae. A single Golgi body with swelled cisternae lies beneath the flagellum, and each cell has an ejectile organelle that putatively releases a cylindrical structure. A vacuole, or cluster of vacuoles, contains the putative carbohydrate storage product.

picture info	Heterokont Heterokonts are a group of protists (formally referred to as Heterokonta, Heterokontae or Heterokontophyta). The group is a major line of eukaryotes. Most are algae, ranging from the giant multicellular kelp to the unicellular diatoms, which are a primary component of plankton. Other notable members of the Stramenopiles include the (generally) parasitic oomycetes, including ''Phytophthora'', which caused the Great Famine of Ireland, and ''Pythium'', which causes seed rot and damping off. The name "heterokont" refers to the type of motile life cycle stage, in which the flagellated cells possess two differently arranged flagella (see zoospore). History In 1899, Alexander Luther created the term "Heterokontae" for some algae with unequal flagella, today called Xanthophyceae. Later, some authors (e.g., Copeland, 1956) included other groups in Heterokonta, expanding the name's sense. The term continues to be applied in different ways, leading to Heterokontophyta being applie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
