Q:

What do euglena eat?

A:

Quick Answer

Euglena eat green algae, amoebas, parameciums and rotifer. Euglena are single cell organisms so their food sources are small, microscopic organisms along with the energy they can create through photosynthesis. Their green color comes from the green algae they eat and the chloroplasts which play a part in photosynthesis, but some types can be red as well.

Full Answer

Euglena are classified as protists because they do not fit in the animal kingdom or the plant kingdom. When an euglena is feeding, it surrounds the prey through a method called phagocytosis. This method allows the organism to surround its prey and absorb it. As these organisms can feed as both a plant and an animal, it was listed as unclassifiable on the two kingdom biological identification system created by Linnaean. The discovery of these organisms that did not go into either category later spurred the creation of a their division in the system called the Kingdom of Protista.

The euglena are normally found in the largest concentrations on water. When a pond, lake or still body of water has a green or sometimes red film over the top of it, it is highly likely that this film will be made up of euglena. Seeing these organisms in water can be a good indicator that the water is polluted.

    What is Euglena viridis?

    A:

    Euglena viridis is the type species for the genus Euglena, a group of tiny one-celled organisms that swims using flagella and creates energy using chloroplasts. Euglena viridis is spindle shaped and lives in water. It has between one and 15 chloroplasts and a flagellum as long as its body.

  • Q:

    What is the shape of Euglena?

    A:

    The shape of Euglena resembles an elongated or spindle-shaped cell that is 15 to 500 micrometers, or 0.0006 to 0.02 inches, in length. Some species can change their shape as they lack a rigid cellulose wall, and instead have a flexible pellicle.

    How do euglena gracilis reproduce?

    A:

    Euglena gracilis reproduce through a process called mitosis. In order to complete this process, they must be exposed to the right temperature and must be well-fed. Once a Euglena gracilis completes mitosis, it will split its self in two, which results in another Euglena gracilis. The completion of this process is best observed when another eyespot appears on a Euglena gracilis that is splitting in two.

  • Q:

    What are the functions of a Euglena cell?

    A:

    Like algae and plants, Euglena cells contain chloroplasts that allow them to create food through photosynthesis, but they can also take in nutrients from other organisms when light is not available. Euglena are a unique group of single-cell organisms that have some of the same functions as both plants and animals.
