Euglena space unicellular biology classified into the Kingdom Protista, and thePhylum Euglenophyta. Every euglena have actually chloroplasts and can make theirown food by photosynthesis. They are not completely autotrophic though,euglena can likewise absorb food from your environment; euglena usuallylive in quiet ponds or puddles.

Euglena move by aflagellum (plural ‚ flagella), i m sorry is a long whip-like structure thatacts favor a little motor. The flagellum is situated on the anterior(front) end, and twirls in such a way as to pull the cell through thewater. The is attached at an inward pocket dubbed the reservoir. Colorthe reservoir grey and also the flagellum black.

The Euglena isunique in that it is both heterotrophic (must consume food) andautotrophic (can do its own food). Chloroplasts in ~ the euglenatrap sunshine that is provided for photosynthesis, and also can be viewed asseveral rod prefer structures throughout the cell. Color thechloroplasts green. Euglena also have one eyespot at the anteriorend the detects light, it deserve to be seen close to the reservoir. This helpsthe euglena discover bright locations to gather sunshine to make their food. Colorthe eyespot red. Euglena can also gain nutrient by soaking up themacross their cell membrane, therefore they end up being heterotrophic when lightis no available, and also they can not photosynthesize.

The euglena has astiff pellicle external the cell membrane the helps it save its shape,though the pellicle is rather flexible and some euglena deserve to beobserved scrunching up and 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 also the nuclear source pink.

The internal of thecell has a jelly-like liquid substance called cytoplasm. Colorthe cytoplasm light yellow. Towards the posterior that the cabinet is astar-like structure: the contractile vacuole. This organelle helps thecell remove excess water, and without that the euglena could take in somemuch water due to osmosis the the cell would certainly explode. Color thecontractile vacuole orange.

Color the Euglenaaccording come the directions. Organelles have the right to be identified based ontheir descriptions and locations answer the adhering to questions

1. Space euglena imreparable cells or multicellular?

2. What Kingdom carry out euglena belong to? What Phylum?

3. What organelle carries the end photosynthesis?

You are watching: How does the euglena obtain food

4. ~ above which finish is the flagellum located?

5. Specify autotrophic.

6. Specify heterotrophic.

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

8. What is the eyespot used for?

9. What is the duty of the nucleus?
