  2. Euglena - Wikipedia

    en.wikipedia.org/wiki/Euglena

    Euglena is a genus of single cell flagellate eukaryotes. It is the best known and most widely studied member of the class Euglenoidea, a diverse group containing some 54 genera and at least 200 species. [1] [2] Species of Euglena are found in fresh water and salt water.

  3. Euglenales - Wikipedia

    en.wikipedia.org/wiki/Euglenales

    Euglenales consists mostly of freshwater organisms, in contrast to its sister Eutreptiales which is generally marine. Cells have two flagella, but only one is emergent; the other is very short and does not emerge from the cell, so cells appear to have only one flagellum. [3]

  4. Euglenaceae - Wikipedia

    en.wikipedia.org/wiki/Euglenaceae

    Euglenaceae show the most morphological diversity within the class Euglenophyceae. [3] They are mostly single-celled organisms, except for the genus Colacium.They are free-living or sometimes inhabiting the digestive tracts of animals. [1]

  5. Euglena gracilis - Wikipedia

    en.wikipedia.org/wiki/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.

  6. Euglenid - Wikipedia

    en.wikipedia.org/wiki/Euglenid

    A prolonged absence of light or exposure to harmful chemicals may cause atrophy and absorption of the chloroplasts without otherwise harming the organism. A number of species exists where a chloroplast's absence was formerly marked with separate genera such as Astasia (colourless Euglena) and Hyalophacus (colourless Phacus). Due to the lack of ...

  7. Excavata - Wikipedia

    en.wikipedia.org/wiki/Excavata

    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 ...

  8. Euglena viridis - Wikipedia

    en.wikipedia.org/wiki/Euglena_viridis

    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 .

  9. Euglenozoa - Wikipedia

    en.wikipedia.org/wiki/Euglenozoa

    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.
