  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. 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.

  4. 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 .

  5. Euglenaceae - Wikipedia

    en.wikipedia.org/wiki/Euglenaceae

    As with other euglenids, cells in the Euglenaceae are surrounded by a series of proteinaceous strips called the pellicle; the pellicle can stretch in most genera, allowing the cell to contract, creating a type of movement called metaboly.

  6. Euglenid - Wikipedia

    en.wikipedia.org/wiki/Euglenid

    Euglenids are commonly found in fresh water, especially when it is rich in organic materials, but they have a few marine and endosymbiotic members. Many euglenids feed by phagocytosis, or strictly by diffusion. A monophyletic subgroup known as Euglenophyceae have chloroplasts and produce their own food through photosynthesis.

  7. 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]

  8. Phacus - Wikipedia

    en.wikipedia.org/wiki/Phacus

    Phacus are commonly found in freshwater habitats all over the world. Many species of this genus have been discovered in several countries, including Japan, the United States, Portugal, Brazil, Korea and the Philippines. [1] [6] [7] Different members of the genus have been found in temperatures ranging from 11.4 to 21.6 °C, and a pH between 6.2 ...

  9. Euglena sanguinea - Wikipedia

    en.wikipedia.org/wiki/Euglena_sanguinea

    Euglena sanguinea is a species of the genus Euglena.The red colour is due to the presence of astaxanthin and the cells can be populous enough to colour water red. The pigment is used to protect the chloroplasts from light that is too intense, but as the light levels change the cells can take on a green colour as the red pigment is moved to the centre of the cells.
