Euglena room unicellular biology classified right into the Kingdom Protista, and also thePhylum Euglenophyta. All euglena have actually chloroplasts and also can do theirown food by photosynthesis. They space not totally autotrophic though,euglena can likewise absorb food from their environment; euglena usuallylive in quiet ponds or puddles.

Euglena relocate by aflagellum (plural ‚ flagella), i beg your pardon is a lengthy whip-like framework thatacts favor a small motor. The flagellum is situated on the anterior(front) end, and twirls in such a way as to traction the cell with thewater. That is attached in ~ an inward pocket dubbed the reservoir. Colorthe reservoir grey and also the flagellum black.

The Euglena isunique in the it is both heterotrophic (must consume food) andautotrophic (can make its own food). Chloroplasts in ~ the euglenatrap sunlight that is supplied for photosynthesis, and can be checked out asseveral rod choose structures transparent the cell. Color thechloroplasts green. Euglena likewise have an eyespot in ~ the anteriorend the detects light, it deserve to be seen near the reservoir. This helpsthe euglena find bright areas to gather sunlight to do their food. Colorthe eyespot red. Euglena can likewise gain nutrients by absorbing themacross your cell membrane, therefore they come to be heterotrophic when lightis not available, and they can not photosynthesize.

The euglena has astiff pellicle exterior the cabinet membrane that helps it keep its shape,though the pellicle is rather flexible and also some euglena deserve to beobserved scrunching up and also moving in an inchworm kind fashion. Colorthe pellicle blue.

In the facility of thecell is the nucleus, which contains the cell"s DNA and also controls thecell"s activities. The nucleolus can be checked out within the nucleus. Colorthe cell core purple, and the nucleolus pink.

The inner of thecell includes a jelly-like fluid substance referred to as cytoplasm. Colorthe cytoplasm irradiate yellow. Toward the posterior the the cell is astar-like structure: the contractile vacuole. This organelle helps thecell remove excess water, and without that the euglena might take in somemuch water because of osmosis that the cell would certainly explode. Color thecontractile vacuole orange.

Color the Euglenaaccording to the directions. Organelles can be figured out based ontheir descriptions and locations answer the complying with questions

1. Room euglena unicellular or multicellular?

2. What Kingdom do euglena belonging to? What Phylum?

3. What organelle carries out photosynthesis?

You are watching: Is euglena an autotroph or heterotroph

4. Top top which end is the flagellum located?

5. Specify autotrophic.

6. Specify heterotrophic.

7. Explain the two methods in i m sorry the euglena obtain their nutrients.

8. What is the eyespot offered for?

9. What is the duty of the nucleus?
