euglenid การใช้

• Most phagotrophic euglenids have two flagella, one leading and one trailing.
• Those that endosymbiosed a green alga include the euglenids and chlorarachniophytes ( = chloroplasts ).
• Some other euglenozoa feed through absorption, and many euglenids possess chloroplasts and so obtain energy through photosynthesis.
• The chloroplasts in euglenids and chlorarachniophytes were acquired from ingested green algae, and in the latter retain a nucleomorph ( vestigial nucleus ).
• It is a precursor of lysine in the alpha-aminoadipate pathway which occurs in a few lower fungi, the higher fungi, and euglenids.
• The chloroplasts of euglenids and chlorarachniophytes appear to be captured green algae, whereas those of other photosynthetic eukaryotes, such as heterokont algae, cryptophytes, haptophytes, and dinoflagellates, appear to be captured red algae.
• In contrast, most other algae ( e . g . brown algae / diatoms, haptophytes, dinoflagellates, and euglenids ) not only have different pigments but also have chloroplasts with three or four surrounding membranes.
• The euglenid genus " Khawkinea " is named in honor of Haffkine's early studies of euglenids, first published in French journals with the author name translated from cyrillic as " Mardoch閑-Woldemar Khawkine ".

• Green algae have been taken up by the euglenids, chlorarachniophytes, a lineage of dinoflagellates, and possibly the ancestor of the chromalveolates Many green algal derived chloroplasts contain pyrenoids, but unlike chloroplasts in their green algal ancestors, starch collects in granules outside the chloroplast.
• Groups claimed by protozoologists and phycologists include euglenids, dinoflagellates, cryptomonads, haptophytes, glaucophytes, many heterokonts ( e . g ., chrysophytes, raphidophytes, silicoflagellates, some xanthophytes, proteromonads ), some monadoid green algae ( volvocaleans and prasinophytes ), choanoflagellates, bicosoecids, ebriids and chlorarachniophytes.
• Euglenid, with plastids, rigid, flattened cells, most species very flat and leaf-shaped, often with ridges, folds or grooves running helically or longitudinally, giving an irregular or triradiate cross-section; many species with a long posterior spine, many twisted, flagella, eyespot and flagellar swelling as in Euglena; chloroplasts usually small, discoid, numerous, without pyrenoids; a few species ( e . g . " P . splendens " ) have large flat chloroplasts with pyrenoids; paramylon is typically deposited as a few large granules ( often rings ) together with many small ones; canal opening subapical; no cysts palmelloid stages rare; speciose, contemporary studies indicate that the genus is not monophyletic or holophyletic; type species : " P . longicauda " ( Ehrenberg, 1833 ) Dujardin, 1841 ..
