What are protists? • Very diverse group of organisms containing over 200,000 species • NOT members of the kingdoms plantae, animalia, fungi or bacteria • Eukaryotes • Most are unicellular How are protists classified? • According to the way they obtain nutrition: – Autotrophs (plant-like) – Heterotrophs (animal-like) – Decomposers and parasites (fungus-like) Animal like protists (protozoans) are distinguished from each other by the way they… Types of movements: 1.Zooflagellates (flagella) Types of movements: 2. Sarcodine (Extension of cytoplasm) Types of movements: 3. Ciliates (cilia) Animallike Protists: Sporozoans • Parasitic to animals –Do not move on their own Drill Partners • Turn to your neighbor and drill one another on the four categories of animallike protists and how they move. • Make certain you both know the four categories and can recall them from memory. Protists that perform photosynthesis are grouped into a category called: Commonly called… Unicellular plantlike protists are: Euglenophytes Chrysophytes Diatoms Dinoflagellates Plantlike protist that have two flagella BUT NO CELL WALL Among the most abundant and beautiful organisms Half their life is photosynthetic; the other half is heterotrophic Heterotrophs that absorb nutrients from dead or decaying organic matter Fungus-like protist include: 1.Slime molds -Thrive on dead or decaying organic matter in water -Plant parasites on land Ticket Out the Door What characteristics do these organisms have that place them in the Kingdom Protista?
