Comparisons of Single-celled Organisms

Euglena

• Move by flagellum• Known for a unique feature—eye

spot• Some contain chlorophyll• Some are common in fresh water

Amoeba

• Move by cytoplasmic streaming• Surrounds food and engulfs it

using pseudopods

Paramecium

• Most complex and specialized of the protists

• Moves by cilia (hairlike projections)

Volvox

• A colony of ciliates• Some contain chlorophyll
