A eukaryote that is not a plant animal or fungus Eukaryotes are cells that have a nucleus (protists are NOT bacteria) Most protists are unicellular and live in water

Watch Protista Video http://www.youtube.com/watch?v=-zsdYOgTbOk

Usually motile Heterotrophic – must consume food Examples: ameba, paramecium Classified by how they move

Move using a flagella

Move using cytoplasmic extensions called pseudopodia (“false feet”) Movement is also called ameboid movement

Watch the Amoeba Video http://www.youtube.com/watch?v=Aa0cvmsD_2Q

Protists that move using cilia Ex: Paramecium

Paramecium join at the mouth pore and exchange DNA from the micronucleus Afterward, they divide (mitosis) and the offspring are different from the original parent This is a form of SEXUAL reproduction

Plantlike Protists: Unicellular Algae Plantlike Protists: Unicellular Algae *Contain chlorophyll and carry out photosynthesis *Commonly called algae *Examples: Euglenophytes, chrysophytes, diatoms, dinoflagellates

Euglena Live in water Have flagella for movement Use chloroplasts for photosynthesis, Can turn into heterotrophs if they are kept in the dark Eyespot used for sensing light and dark

Funguslike Protists *Heterotrophs *Decomposers *Called slime molds and water molds *Water molds responsible for the Irish Great Potato Famine Water mold responsible for the Irish Great Potato Famine Water molds decompose dead animals in aqueous environment
