Copy Down Questions for the Protist Video How can you examine a protists? Why did the discovery of these organisms complicate the classification system? What are the blue structures? What are the simplest protist organisms? What does the euglena do at nightfall? How does amoeba protect themselves from predators? What are the most advance forms of single cell life? Where will you find paramecium in abundance and why? What is the preferred diet of protists? How do algae get their energy? Who do algae live symbiotically with?

Kingdom Protista

Protists Eukaryotic Most are unicellular, so are multicellular Some are autotrophs, some are heterotrophs, and some are both. Food for many other organisms in the food chain Very diverse group

Animal-like protist: Protozoans Ex. Amoeba, paramecium

Amoeba Moves by means of extensions of the cytoplasm called a pseudopod.

–These extensions is not only used for movement, but to capture food. –The Ameoba is heterotrophic; it pulls other microorganisms into its cell body by endocytosis.

Paramecium Is more complex Uses hair-like cilia to move and capture food. Heterotrophic

Paramecium The tiny cilia can be seen all over the paramecium’s surface, so this allows the paramecium to move faster than all other protists.

Plant-like Protists Some are autotrophs and contain chlorophyll so they can carry out photosynthesis. Ex. Algae, Euglena, and Diatoms

Algae They have no roots, stems, leaves, or flowers. Many types of algae contain pigments other than chlorophyll; they may be brown, red, or even golden color. They are an important food source for many types of animals They DO NOT MOVE

Ex. Golden Algae

Green Algae

Brown Algea

Red Algae

Diatoms Unicellular Photosynthetic Have a glass-like outer shell Some have Flagellum When diatoms die, the glass-like material collects at the bottom of the ocean called diatomaceous earth.

Euglena Mosly Aquatic Found in Freshwater Contain Chlorophyll and Autotrophic However, the Euglena can also take in food from its environment, so it is heterotrophic also.

Euglena - They have a sensitive eyespot that helps them find sunlight - They move around by using a whip-like flagellum.

Fungus-like Protists Ex. Slime Molds, downy Mildews, and water molds

Characteristics They decompose dead organisms. They are able to move from place to place for at least part of their life cycle. 3. Many are colorful.

Slime Molds

Downy Mildews

Water Molds
