KEY CONCEPT Animal-like protists are single-celled heterotrophs that can move.

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

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

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

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

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

Some animal-like protists cause disease. Protists cause some well-known infectious diseases. sporozoites human liver liver cells developed parasites red blood cells 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. Malaria Infection
