Bellringer Red algae, green algae, and brown algae are all examples of protists that are_________________. Plant Like Animal Like Fungi Like Kingdom Protista Protists: What are they? Protozoans Animal-like Protists Characteristics Heterotrophs- consume food Move from place to place Unicellular (one celled) 4 groups based on how they move Protozoans Sarcodines Sarcodines Have pseudopods (cell bulge movement) Contractile vacuoles- remove extra water from the cells Also have: Cytoplasm Food vacuole (breaks down food) Nucleus Cell membrane (very thin and flexible so no definite shape) Example: Amoeba Turn to Amoeba Drawing and Label Ciliates have: Protozoans Ciliates Cilia- long hairlike projections that move with wavelike motion Contractile vacuoles (collect excess water from cytoplasm) Large and small nucleus Cytoplasm Oral groove (used to move water containing food to vacuole) Food vacuole (food is broken down and distributed here) Pellicle (stiff, flexible covering) Anal Pore (wastes leave here) Example: Paramecium Turn to Paramecium drawing and label Protozoans Sporozoans These are characterized as Parasites (live off of another living thing) Move by flagella, hosts, or slime Example Plasmodium Causes Malaria- moves from person to person by mosquito Protozoans Flagellates Have a Long whip-like flagella to move Example Giardia Plant Like Protists Autotrophs- make their own food through photosynthesis and therfore have Chloroplasts Examples: Diatoms: glass-like with cell walls Euglenoids: Euglena---which is autotrophic but can also be heterotrophic when no sunlight is available Dinoflagellates- always have 2 flagella when they move, the dinoflagellate twirls like a toy top Red, Green, & Brown Algae: seaweeds Euglenoid- turn to euglena page and label Red, Brown and Green Algae Fungus-Like Protists Like a fungus because they: Un-like fungus because they: Are heterotrophs Have cell walls Use spores to reproduce Move at some point in their life cycle Examples: Slime molds Water molds Downy molds
