2. What are Protozoans???
 unicellular (single-celled), eukaryotic
organisms.
 They are often, but not always motile,
using pseudopodia, cilia or flagella
 osmoregulation is by means of a
contractile vacuole
 “animal-like”

4. PARASITIC

6. Free-living
Protozoa

8. What are free-living
protozoans?
 Habitat: fresh and salt water, soil and
