Euglena is a genus of single cell flagellate eukaryotes. ... a form of cell division. ... This feature was incorporated into Ehrenberg's name for the new genus ...
The phagotrophs, although paraphyletic, have historically been classified under the name of Heteronematina. [9] In addition, euglenids can be divided into inflexible or rigid euglenids, and flexible or metabolic euglenids which are capable of 'metaboly' or 'euglenid motion'. Only those with more than 18 protein strips in their pellicle gain ...
Euglena viridis is a freshwater, single cell, mixotroph microalgae bearing a secondary chloroplast. [1] Their chloroplast is bounded by three layers of membrane without a nucleomorph . [ 2 ] Normally, it is 40–65 μm long, slightly bigger than other well-known Euglena species: Euglena gracilis .
Euglena gracilis is a freshwater species of single-celled alga in the genus Euglena. It has secondary chloroplasts , and is a mixotroph able to feed by photosynthesis or phagocytosis . It has a highly flexible cell surface, allowing it to change shape from a thin cell up to 100 μm long to a sphere of approximately 20 μm.
The family Euglenaceae is also known by the name Euglenidae. The origin of this dual naming system is because of the history of protists. Euglenids have been treated as both algae and protozoans , which are governed by separate nomenclature codes . [ 2 ]
Many have a conspicuous ventral feeding groove with a characteristic ultrastructure, supported by microtubules—the "excavated" appearance of this groove giving the organisms their name. [ 3 ] [ 6 ] However, various groups that lack these traits are considered to be derived excavates based on genetic evidence (primarily phylogenetic trees of ...
The genus name is believed to have originated from the Greek word Phakos, meaning lentil or lens. [3] This may be due to the general round or oval shape of the many species that are part of this genus. Its origins date back to the nineteenth century, in France, where it first received publication and establishment by Dujardin. The genus name is ...
For example, one family has the name Euglenaceae under the ICNafp and the name Euglenidae under the ICZN. As another example, the genus name Dinema is acceptable under the ICZN, but illegitimate under the ICNafp, as it is a later homonym of an orchid genus, so that the synonym Dinematomonas must be used instead.
