1. Kingdoms and Domains

2. HOW DO WE ORGANIZE LIVING THINGS? We name all organisms using many names: K ingdomKeep P hylumPonds C lassClean O rderOr F amilyFroggies G enusGet S peciesSick Each level is called a “taxon” specificspecific

3. Classifying Kingdoms Nutrition Heterotrophic -consumes living or dead organisms to obtain energy Autotrophic -uses sun’s energy -makes own food # of cells Unicellular -one cell Multicellular -more than one cell -many cells Reproduction Asexual -offspring produced from a single parent (genetically identical to parent) Sexual -production of offspring from fusion of 2 sex cells (offspring differ from parents)

4. Classifying Kingdoms Habitat -where does the organism live? Cell Type ProkaryoticEukaryotic -circular chromosome (plasmid) -no membrane bound organelles (e.g. no true nucleus) -very small (less than 2 um) -reproduce by binary fission -double stranded chromosomes in nucleus -membrane bound organelles -larger (10-100 um) -reproduce by mitosis or meiosis

5. SIX KINGDOMS Each kingdom has many phyla Each phylum has many classes Each class has many orders Etc.

7. Archaebacteria are ancient bacteria live in extreme environments Prokaryotes Halophiles (salt marshes), Acidophiles (acidic environments), Thermophiles (hot springs)

8. Eubacteria bacteria with a broad habitat range prokaryotes

9. Protista are mostly single celled eukaryotes (have nucleus). animallike, plantlike with chloroplasts, and fungilike Examples are paramecium, amoeba, algae.

10. Fungi once classified as plants however cell walls composed of chitin (not cellulose) are heterotrophic (consume) multicellular Examples are mould, yeast, mushrooms.

11. Plantae multicellular autotrophic (produce carbohydrates by photosynthesis) organisms Cell walls are composed of cellulose. Examples are mosses, trees, ferns…

12. Animalia multicellular heterotrophic organisms no cell wall subdivided into invertebrates and vertebrates

13. Apparently, the primordial cell was a Pac Man ghost???
