1. Protista: The Kingdom of Protists By Red Sammons Michael McMillan And Brett Andrews

2. Structure of Protists - Most are Unicellular - Most are simple Eukaryotic structures - Some are multi-cellular but are very simple - Membrane bound organelles - Unicellular protists are specialized

3. Types of Protists Algal protists – Plant like unicellular organisms Fungal protists – Slime molds – Characteristics of plants and animals Protozoa – Animal like unicellular organisms

4. Major Phyla & Species Protophyta: Euglenoids, Golden Algae, Fire Algae Gymnomycota: True slime molds Protozoa: Sarcodines, Ciliates, Sporozoans, Flagellates

5. Feeding Autotrophic and Heterotrophic, some are both They live on animals or decaying materials Euglenoids make their own food Golden Algae and Dinoflagellates are photosynthetic All protozoans are heterotrophic

6. Reproduction Use both sexual and asexual reproduction Golden Algae – Diatoms conduct mitosis multicellular algae life cycle sporophyte gametophyte

7. Algal Protists Use flagella for movement Three main types: Euglenoids, Pyrophytes, Rhodophytes All algal protists are aquatic Uses sexual, not asexual reproduction Seaweed is a form of algal protists

8. Slime Molds Fungus like organisms Found in damp areas and decaying vegetation Non-photosynthesizing Cellular – Independent, Haploid cells – Form a mass of individual cells (pseudoplasmodium) Acellular – Masses of cytoplasm (plasmodium) – Spread thinly over square meters

9. Protozoa Eukaryotic Reproduce by mitosis Sarcodines: Blob-like and asymmetrical amoebae Two types of sarcodines (foraminifera, radiolaria) have hard shells Flagellates: All possess a whip-like flagellum These are propelled by the flagellum moving back and forth Ciliate: Has a number of hair-like cilia on its surface These propel the organisms by waving in a synchronous motion Sporozoans: Have no organs for movement Are very complex animals, many are parasites
