1. Protista, Fungi, Bacteria, and Viruses

2. Protista A protist is any organism that is not a plant, animal or fungus - Eukaryotes (have nucelus) -Unicellular or multicellular -Heterotrophs (obtain food) or autotrophs (make food) -May be categorized into animal-like (movement), plant-like (algae), or fungus-like (water molds)

3. Protista Some live freely; others on parasites Most live in water EX/ amoeba, paramecium, algae, mold **Algae benneficial- produces oxygen and food for lower organisms on food chain, fertilizers..ect http://www.youtube.com/watch?v=-zsdYOgTbOk

4. Kingdom Fungi Eukaryotes (Have nucelus) Unicellular or multicellular, Heterotrophs, autotrophs, saprophytic (break down dead matter) Some are parasitic and obtain nutrients from living hosts **Benneficial- mushrooms as food, penicillin production, eat decaying matter, yeast (beer/bread)

5. Fungi Structure: Have cell walls that contain chitin Do not undergo photosynthesis Hyphae:Long branching structure of fungi Mycelium: Vegetative part of fungi and reproductive part Mycologist (scientist who study fungi) are said to have only identified 5% of all fungi

6. Largest living thing in the world? 2400 yrs old and 2200 acres (1665 football fields) in Oregon

7. Bacteria “germs” Classified into 3 groups based on their shapes- 1.Cocci: Round shaped 2.Bacilli: Rod shaped 3.Spirilli: Spiral shaped Bacteria Structure

8. Bacteria Respiration: – Obligate anaerobes - cannot survive in the presence of atmospheric oxygen. – Facultative anaerobes - can live with or without atmospheric oxygen. – Obligate aerobes - cannot survive without atmospheric oxygen. *Beneficial uses? -digestion, building up/breaking down organic compounds, wastes, tobacco, immune system

9. HOW TO PREVENT THE SPREAD OF BACTERIA Wash hands Disinfect surfaces Sanitize Store foods at Proper temps

10. Viruses Surrounded by a protein coat called CAPSID NOT considered living 1/100 th size of bacteria Has only RNA or DNA (not both)

11. Viruses Reproduces only after infecting a host cell (Can not live independently)Reproduces quickly! Lytic Cycle- Destroys cell by replicating virus Nucleic acids instead of the cells. Then it infects other cells Lysogenic Cycle-DNA integrated into cells reproduction- does not destroy cell.
