PROTISTSThe “Little Guys”
BUT… There are some general characteristics they all share: Unicellular (made of one cell)
Eukaryotes (have a nucleus)
Live in moist environments

• Heterotrophs• Classified by
how they move
• Autotrophs• Have cell
walls
• Heterotrophs• Have cell walls
- Sarcodines- Ciliates- Zooflagellat
es- Sporozoans
PROTOZOANS
Move using PSEUDOPODS (“false feet”), bulges of the cell membraneExample: AMOEBA
Pseudopod
Sarcodine Animations/Videos
PROTOZOANS
Move using CILIA, tiny hair-like projections that move in a wavelike motion, acting like oarsExample: PARAMECIUM
Cilia
Ciliate Animations/Videos
PROTOZOANS
Move using FLAGELLA, a long, whip-like structureExample: EUGLENA Flagella
