  1. Kingdom Protista

  2. All are eukaryotes (have a nucleus) Animal-like protists (Protozoans) Plant-like protists (Algae) Fungus-like protists (slime molds, water molds) Protists are a diverse group

  3. Animal-like Protists • Eat other organisms • Classified by movement: • Ciliates move using small hairs called cilia • Flagellates move using 1 or 2 whip-like tails called flagella • Sarcodines move with pseudopodia • Sporozoans do not move, they are parasites

  4. Ciliates • Paramecia move using tiny waving hairs to glide through the water

  5. Flagellates • Some flagellates are animal-like because they move and eat other things, but they can also photosynthesize like a plant!

  6. Sarcodines • Amoeba move by cytoplasmic streaming (like the Blob!). The projections that are formed are called pseudopodia.

  7. Sporozoans • Malaria is caused by a sporozoan that is spread by mosquito bites.

  8. Classified by color and whether they are single celled or multi-cellular. They are much simpler than true plants. Plant-like ProtistsAlgae are able to photosynthesize

  9. Slime molds start their life cycle like animal-like protists Later they stop moving, form a fruiting body (similar to a mushroom), and make spores Fungus-like ProtistsSlime molds have dual lives!

  10. Protists are important • Slime molds act as decomposers to recycle nutrients from dead plants and animals or animal waste. • Algae are the major photosynthesizers on our planet, producing more food and oxygen than the true plants • Protists form the beginning of most food chains • Some are important disease pathogens of plants and animals.
