Euglena room unicellular biology classified into the Kingdom Protista, and thePhylum Euglenophyta. All euglena have chloroplasts and can make theirown food by photosynthesis. They room not fully autotrophic though,euglena can additionally absorb food from their environment; euglena usuallylive in quiet ponds or puddles.

Euglena relocate by aflagellum (plural ‚ flagella), which is a long whip-like structure thatacts favor a tiny motor. The flagellum is situated on the anterior(front) end, and also twirls in together a way as to traction the cell through thewater. The is attached at an inward pocket called the reservoir. Colorthe reservoir grey and the flagellum black.

The Euglena isunique in that it is both heterotrophic (must consume food) andautotrophic (can make its very own food). Chloroplasts within the euglenatrap sunlight that is offered for photosynthesis, and also can be watched asseveral rod favor structures throughout the cell. Color thechloroplasts green. Euglena likewise have one eyespot in ~ the anteriorend that detects light, it have the right to be seen close to the reservoir. This helpsthe euglena uncover bright locations to gather sunshine to make their food. Colorthe eyespot red. Euglena can also gain nutrient by absorbing themacross their cell membrane, for this reason they end up being heterotrophic when lightis no available, and also they can not photosynthesize.

The euglena has actually astiff pellicle outside the cabinet membrane that helps it save its shape,though the pellicle is rather flexible and also some euglena can beobserved scrunching up and also moving in one inchworm kind fashion. Colorthe pellicle blue.

In the facility of thecell is the nucleus, which consists of the cell"s DNA and controls thecell"s activities. The nucleolus deserve to be viewed within the nucleus. Colorthe cell core purple, and also the core source pink.

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

Color the Euglenaaccording come the directions. Organelles have the right to be identified based ontheir descriptions and locations price the complying with questions

1. Room euglena uncellular cells or multicellular?

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

3. What organelle carries the end photosynthesis?

You are watching: What is the function of the eyespot in the euglena

4. On which finish is the flagellum located?

5. Specify autotrophic.

6. Define heterotrophic.

7. Explain the two means in which the euglena get their nutrients.

8. What is the eyespot provided for?

9. What is the role of the nucleus?
