  1. KEY CONCEPTAnimal-like protists are single-celled heterotrophs that can move.

  2. macronucleus contractile vacuole food vacuole oral groove micronucleus cilia Animal-like protists move in various ways. • Animal-like protists are often called protozoa.

  3. Protozoa with flagella are zooflagellates. • flagella help zooflagellates swim • more than 2000 zooflagellates

  4. Some protists move with pseudopods. • change shape as they move • amoebas

  5. Some protists move with pseudopods. • change shape as they move • amoebas • foraminifera

  6. Some protozoa move with cilia. macronucleus contractile vacuole food vacuole oral groove micronucleus cilia • cilia help protists swim and capture food • more than 8000 ciliates

  7. Protists cause some well-known infectious diseases. human liver sporozoites liver cells developed parasites red blood cells Some animal-like protists cause disease. • Malaria is caused by Plasmodium and spread by mosquitoes. • Sleeping sickness is caused by Trypanosoma and spread by flies. • A giardia infection is caused by Giardia and spread through water.
