Animal-like Protists

• Animal-like protists include the phyla Protozoa, Ciliophora, Sarcomastigophora, and Apicomplexa. For locomotion, protozoa use pseudopodia, ciliates use cilia, and sarcomastigophorans use flagella.

Vocabulary pseudopodium (p. 506) amoeboid movement (p. 506) test (p. 507) cilium (p. 507)

pellicle (p. 508) oral groove (p. 508) mouth pore (p. 508)

• Ciliates reproduce asexually by binary fission and sexually by conjugation.

• Apicomplexans lack locomotion, so they are parasites.
