Animal-like protists move in various ways.
  • Animal-like protists are often called protozoa.
slide3
Protozoa with flagella are zooflagellates.
  • flagella help zooflagellates swim
  • more than 2000 zooflagellates
slide4
Some protists move with pseudopods.
  • change shape as they move
  • amoebas

Some protists move with pseudopods.
  • change shape as they move
  • amoebas
  • foraminifera
slide6
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
