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
