Comparisons of Single-celled Organisms
4
Euglena

• Move by flagellum
• Known for a unique featureeye spot
• Some contain chlorophyll
• Some are common in fresh water

5
Amoeba

• Move by cytoplasmic streaming
• Surrounds food and engulfs it using pseudopods

6
Paramecium

• Most complex and specialized of the protists
• Moves by cilia (hairlike projections)

7
Volvox

• A colony of ciliates
• Some contain chlorophyll
