Key concept animal like protists are single celled heterotrophs that can move

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


Animal like protists move in various ways

macronucleus

contractile vacuole

food vacuole

oral groove

micronucleus

cilia

Animal-like protists move in various ways.

  • Animal-like protists are often called protozoa.


Key concept animal like protists are single celled heterotrophs that can move

Protozoa with flagella are zooflagellates.

  • flagella help zooflagellates swim

  • more than 2000 zooflagellates


Key concept animal like protists are single celled heterotrophs that can move

Some protists move with pseudopods.

  • change shape as they move

  • amoebas

Key concept animal like protists are single celled heterotrophs that can move

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


Some animal like protists cause disease

Protists cause some well-known infectious diseases.

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.
