1. It’s ALIVE!!! Or, is it? An Unger Power Point

2. All organisms have 6 characteristics Cells Response to stimulus Reproduction DNA/”Life Molecule” Use Σ Grow & develop

3. Cell Subunit of life Membrane-bound 2 types Prokaryote Eukaryote

4. Response to Stimulus React to change Maintain homeostatis

5. Reproduction Ability to produce offspring Asexual Reproduction ONE parent Sexual Reproduction TWO parents

6. DNA/”Life Molecule” DeoxyriboNucleic Acid Passes on hereditary information

7. Use Σ Organisms take in and use energy Metabolism Sum of all chemical reactions YOU are walking, talking, living, breathing CHEMICAL REACTIONS!

8. Types of Σ

9. Chemicals of life Carbohydrates Sugar/  Lipids Fat/storage for Σ Proteins Some Σ / made of amino acids Nucleic Acids DNA & RNA

10. One sentence to rule them all. Nucleic acids provide the information to make proteins, which are then used to break down carbohydrates and lipids to release energy.

11. Grow & Develop Grow Get bigger Develop Δ form

12. Necessities of life Food Make it (producer/autotroph) Get it (consumer/heterotroph) OTHER (decomposer) Water Allows metabolism to take place Air CO 2 and O 2 Shelter Rest & security

13. Proof of LIFE Back in the day…spontaneous generation 2 experiments prove LIFE from LIFE

14. Redi…an Italian doc (1600’s) Fly babies only came from flies!!!!

15. Pasteur…a Frenchman (1800’s) The air also let in bacteria. LIFE from LIFE!!!

16. How life is organized…

17. Classification HOW we arrange/group organisms based on similarities EIGHT levels Domain Kingdom Phylum Class Order Family Genus Species Does King Philip Come Over For Green Soup?

18. What is missing? DOMAIN!!! EUKARYOTE

19. Taxonomy THE Science of identifying & labeling/naming organisms Carolus Linnaeus (Swedish botanist 1750s) Binomial Nomenclature 2 name system Genus & Species FIRST letter of Genus is CAPITAL first letter of species is lowercase BOTH are ALWAYS italicized or underlined

21. Branching Diagrams/Cladogram Arrows point TO living organism Characteristic/trait ALONG branch What is missing?

22. Classification of ALL Life! Domain Eukaryote Domain Prokaryote Domain Bacteria Archeabacteria & Eubacteria ProtistaFungiPlantaeAnimalia Unicellular, Prokaryotic, Auto & Heterotrophs Unicellular, Prokaryotic, Auto & Hetero Multicellular, Eukaryote, Decomposer Multi, Eukaryote, AUTO Multi, Eukaryote, HETERO

23. Dichotomous Keys A tool that helps its user identify natural objects. Dichotomous means "divided into two parts.” Each step has TWO choices
