1. Objective Compare the structures and functions of the following single-celled organisms:
Euglena
Amoeba
Paramecium
Volvox

2. Essential Question: What are the characteristics of the following single-celled organisms? Euglena Amoeba Paramecium Volvox

3. Euglena Environment: fresh and salt water
Movement: flagella (tail-like)
Food:
Heterotrophic- engulfs full cell and absorb them.
Autotrophic- make their own food using chlorophyll.
Reproduction: asexual
Additional Organelle:
Eye spot- senses light and guides Euglena in its direction

4. Euglena

5. Amoeba Environment: Fresh and salt water
Movement: Cytoplasmic Streaming
Changing shape
Food: heterotrophic
They surround their prey and engulf it with a Pseudopodium- (false foot)
Reproduction: asexual
Additional Information: Changes shape

6. Amoeba Eating Paramecium

7. Paramecium Environment: Fresh water Movement: Cilia (hair-like)
Bend and straighten helping propel organism through water.
Food: Heterotrophic
Uses cilia to sweep the food into the cell.
Reproduction: sexual and asexual
Additional Info: Most complex and specialized

8. Paramecium

9. Volvox
Environment: freshwater, unicellular organism called ciliates living in a colony together
Movement: Each cell in the colony has 2 flagella
Eyespots: sense and guide towards light
Food:
Heterotrophic
Eat algae
Autotrophic
makes its food through photosynthesis
Reproduction: asexual and sexual
daughter colonies (offspring) mature and the Volvox bursts open to release them.
