Protists• Most are unicellular

• All live in moist environments

• Are all eukaryotic

—Have cells with nuclei

Page 3: Protists The Junk Drawer Kingdom Notes # 22. Protists Most are unicellular All live in moist environments Are all eukaryotic —Have cells with nuclei.

Animal-like Protists

•Are heterotrophs

•Most are protozoan

are able to move from place to place to obtain their food

•Are unicellular

Protozoans

4 types

pseudopods

ciliates

zooflagellates

sporozoans

Pseudopods•pseudopods: fake feet

—forms when the cell bulges out and fills with cytoplasm —used to respond to changes in environ. like escaping light or temp., and for gathering food—Ex: Ameba

Ciliates

•Have cilia

•Ex: Paramecium

•Hairlike structures that move in a wavelike pattern

•Use to move, get food, sense environ.

Zooflagellates

•Use 1-8 flagella to movewhiplike tail used to move

•Ex: Giardia lamblia—lives in streams and causes hiker’s disease

•Ex: live inside termites

Sporozoans

•Feed on cells and body fluids of host

•Ex: Plasmodium—causes malaria

•Parasites

Fungi-like Protists•Heterotrophs

•Have cell walls

•Use spores to reproduce

•Able to move at some point in lives

•3 types: water molds downy mildew

slime molds

Plant-like Protists

•Commonly called algae

•Autotrophic

•Some live in soil, tree bark, and fresh and salt H2O

•Ex: Euglenoids, dinoflagellates, diatoms, and green, red, and brown algae
