Euglenids or euglenoids are one of the best-known groups of eukaryotic flagellates: single-celled organisms with flagella, or whip-like tails. They are classified in the phylum Euglenophyta, class Euglenida or Euglenoidea.

Mar 11, 2025 · Euglena, genus of more than 1,000 species of single-celled flagellated (i.e., having a whiplike appendage) microorganisms that feature both plant and animal characteristics. Found worldwide, Euglena live in fresh and brackish water rich in organic matter and can also be found in …

Euglenoids are the best-known flagellates of the phylum Euglenozoa. Euglenoids have an outer protein layer called the pellicle. They are unicellular and biflagellate. Examples of euglenoids are Euglena, Trachelomonas, etc.

Structure of Euglenoids: (i) Euglenoids are unicellular flagellate protists. They are without cellulose cell wall. The body is covered by thin and flexible pellicle (= periplast). The pellicle has oblique but parallel stripes called myonemes.

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.

The euglenoids, also known as euglenids, euglenophytes, or euglenoid flagellates, are among the most ancient lineages of eukaryotic algae. Many euglenoids lack plastids, while others possess secondary green or colorless plastids (Whatley 1993) and thus vary in nutritional type.

Euglenoids (Euglenida) are unicellular flagellates possessing exceptionally wide geographical and ecological distribution. Euglenoids combine a biotechnological potential with a unique position in the eukaryotic tree of life.

Oct 13, 2021 · Euglena is a genus of unicellular, freshwater organisms that are very common in ponds and small bodies of water, especially if they are rich in nutrients and consequently high in algae (aka 'pond scum' ). As noted below, Euglena itself is sometimes photosynthetic and is a component of the green sludge in such ponds.

Jul 4, 2020 · Euglena is a motile, single-celled (unicellular) organism that is commonly found in aquatic habitats. They were among the first organisms in the kingdom Protista to be seen under the microscope, looking like a tiny particle making small movements in the water.

Apr 21, 2025 · Euglenoids are distinguished by the absence of a cell wall, but they do contain flexible pellicles made up of protein. All the euglenoids have one or two flagella, by means of which they can swim easily.
