Euglena is a genus of single cell flagellate eukaryotes. (wikipedia.org)
Euglena viridis (O. F. Mueller) Ehrenberg Taxonomic Serial No. Euglena definition, a genus of green freshwater protozoans having a reddish eyespot and a single flagellum, found especially in stagnant waters. (arrownewmedia.biz)
Euglena are single celled organisms that belong to the genus protist. (arrownewmedia.biz)
Euglena is a large genus of unicellular protists: they have both plant and animal characteristics. (arrownewmedia.biz)
Chu (1946) sorted these species into group II under the genus Euglena using the characteristics of chloroplast shape and number and the presence of a naked pyrenoid. (e-algae.org)
Most species of Euglena have photosynthesizing chloroplasts within the body of the cell, which enable them to feed by autotrophy, like plants. (wikipedia.org)
Euglena's chloroplasts are surrounded by three membranes, while those of plants and the green algae (among which earlier taxonomists often placed Euglena) have only two membranes. (wikipedia.org)
Euglena chloroplasts contain pyrenoids, used in the synthesis of paramylon, a form of starch energy storage enabling Euglena to survive periods of light deprivation. (wikipedia.org)
Euglena viridis is a unicellular protozoa with free life typical of freshwater, capable of photosynthesis thanks to chloroplasts. (arrownewmedia.biz)
In some species, such as Euglena mutabilis, both flagella are "non-emergent"--entirely confined to the interior of the cell's reservoir--and consequently cannot be seen in the light microscope. (wikipedia.org)
Species of Euglena were among the first protists to be seen under the microscope. (wikipedia.org)
Currently, there are over 1000 species of Euglena that have been discovered, and many more that have yet to be seen. (arrownewmedia.biz)
Euglena viridis: a species that inhabits stagnant pools, often in great numbers. (arrownewmedia.biz)
The Euglena deses group are common freshwater species composed of E. adhaerens , E. carterae , E. deses , E. mutabilis , and E. satelles . (e-algae.org)
Traditionally, the species of the Euglena deses group (i.e. (e-algae.org)
Eyespot3
Like other euglenoids, Euglena possess a red eyespot, an organelle composed of carotenoid pigment granules. (wikipedia.org)
As the cell rotates with respect to the light source, the eyespot partially blocks the source, permitting the Euglena to find the light and move toward it (a process known as phototaxis). (wikipedia.org)
Chlamydomonas & Euglena viridis / 1000x microscope magnification / DIC Euglena viridis, iğ şeklindedir ve suda yaşar. (arrownewmedia.biz)
Euglena viridis è un protozoo unicellulare a vita libera tipico delle acque dolci, capace di effettuare la fotosintesi grazie ai cloroplasti. (arrownewmedia.biz)
8. Euglena viridis adalah sejenis alga bersel tunggal yang berbentuk lonjong dengan ujung anterior (depan) tumpul dan meruncing pada ujung posterior (belakang). (arrownewmedia.biz)
Euglena viridis, flagella kullanarak yüzer ve kloroplastlar kullanarak enerji üreten küçük tek hücreli bir grup organizma olan Euglena cinsinin türüdür. (arrownewmedia.biz)
Flagella1
Euglena have two flagella rooted in basal bodies located in a small reservoir at the front of the cell. (wikipedia.org)
Asexually2
Euglena reproduce asexually through binary fission, a form of cell division. (wikipedia.org)
Euglena reproduces asexually by binary fission and there's no evidence of sexual reproduction. (arrownewmedia.biz)
Culture2
If a culture of Euglena is examined, most of the animals will be found on the side towards the light. (arrownewmedia.biz)
Since Euglena have features of both animals and plants, early taxonomists, working within the Linnaean two-kingdom system of biological classification, found them difficult to classify. (wikipedia.org)
Thus, the similarities between Euglena and plants would have arisen not because of kinship but because of a secondary endosymbiosis. (wikipedia.org)
Light1
When feeding as a heterotroph, Euglena takes in nutrients by osmotrophy, and can survive without light on a diet of organic matter, such as beef extract, peptone, acetate, ethanol or carbohydrates. (wikipedia.org)
Group1
Pringsheim (1956) classified the E. deses group into the subgroup Serpentes based on cell shape, metabolic degree and chloroplast type. (e-algae.org)
