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.

  • Q:

    What is the structure of the Euglena?

    A:

    According to Kenyon College, the structure of the single-celled eukaryotic Euglena includes a spiral exoskeleton outside of a long, thin cell with a flagellum for motion and, in most cases, several internal chloroplasts. They are capable of both photosynthesis and consuming other organisms in their environment.

  • Q:

    What are the characteristics of Euglena?

    A:

    Euglena are single-celled organisms that live mostly in fresh water, although a few species do live in salt water. They have long tails called flagella, which they use to move through water. Most species of euglena contain chloroplasts and produce their own food through photosynthesis.

    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:

    How do Euglena digest food?

    A:

    According to the Monroe County Women's Disability Network, Euglena digest food like any other protozoa by taking the food into the body and storing it in vacuoles where the nutrition is then spread throughout the body. These small organisms are able to eat food as well as produce it.
