2. Kingdom Protista Fidgety little critters!

3. What is a Protist? Eukaryotic Eukaryotic –Has a nucleus! Mostly single celled Mostly single celled Classified by: Classified by: –MOVEMENT MOVEMENT –OBTAIN FOOD OBTAIN FOODOBTAIN FOOD Animal-like: Animal-like: –Heterotrophic Plant-like: Plant-like: –Autotrophic (have chloroplasts) Fungus-like: Fungus-like: –Parasitic –REPRODUCE REPRODUCE

4. Animal-like Protists: Sarcodinia Movement: Movement: –By pseudopods: Little blobs of cytoplasm Little blobs of cytoplasm Means “Fake Feet” Means “Fake Feet” Consumer Nutrition: Consumer Nutrition: –Surround meal and bring into food vacuole Phagocytosis! Phagocytosis! Reproduction: Reproduction: –Binary Fission Organism: Organism: –Amoeba amoeba

5. Animal-like Protists: Ciliates Movement: Movement: –By cilia: Little “hairs” that beat like oars Little “hairs” that beat like oars Consumer Nutrition: Consumer Nutrition: –Food is swept in by cilia to GULLET –Contractile vacuoles collect and “spit out” water Reproduction: Reproduction: –Binary fission AND conjugation Organism: Organism: –Paramecium caudatum, Stentor coeruleus, Blepharisma

6. Plant-like Protists: Flagellates (Volvox) Colonial organism: Colonial organism: –Hundreds of individual cells “live” together Movement: Movement: –Long, whip-like flagella –Whole colony moves together! Nutrition: Nutrition: –Autotrophic –Contain chloroplasts! (Hence green color!) Reproduction: Reproduction: –Binary fission

7. Euglenophytes: The plant-like animal protist NO CELL WALL: NO CELL WALL: –Has pellicle MOVEMENT: MOVEMENT: –TWO flagella NUTRITION: NUTRITION: –Autotrophic (chloroplasts) –Can be heterotrophic when no sunlight! –Red eye spot helps organism to find sunlight REPRODUCTION: REPRODUCTION: –By binary fission ORGANISM: ORGANISM: –Euglena EYE SPOT
