1. Kingdoms Overview
Six Kingdoms of Life

2. Archaebacteria All prokaryotes (LACK A TRUE NUCLEUS) & unicellular
Live in extreme envts
Methanogens
Halophiles (salt)
Thermophiles (heat)
100 or so species
Chemosynthetic, photosynthetic, & heterotrophic
Possess a cell wall (no peptidoglycan)
Asexual (binary fission)

3. Eubacteria Also prokaryotes Unicellular
Most numerous organisms on Earth- Ubiquitous!!!
Autotrophic & Heterotrophic
Salmonella, E. coli, Streptococcus, L. Baccillus
DECOMPOSERS!
Come in 3 basic shapes: round, rod, spiral

4. Understanding Bacteria

5. Eubacteria continued….
Reproduce asexually (binary fission)
5,000 – 10,000 species
Some are pathogens , but many are beneficial
Cell walls (basis of classification in wall peptidoglycan )

6. CELL PHONES!!!!

7. Flesh Eating Bacteria

8. Protista All eukaryotic “Junk drawer” Multi & Unicellular (colonial)
Some are plant-like (autotrophic – algae), others are animal – like (heterotrophic – protozoa), and others are fungus-like
200,000 species or so
Includes amoebas, paramecia, Euglena, kelp, slime molds, etc.
Largely asexual, (can reproduce sexually in times of environmental stress)

9. The Protists
Amoeba eating
Amoeba eats Parmecium
Protist overview

10. Protista Video!!!

11. Fungi
Eukaryotic
Heterotrophic (feed by absorption – extracellular digestion)
Decomposers
Multicellular (exception of yeast)
Composed of threadlike filaments known as HYPHAE
Non-motile
Cell walls (chitin)
Lack chlorophyll
77,000 – 100,000 species
Mushrooms, mold, yeast, etc.
Sexual reprod. (majority)

12. What are the fungi???

13. Plantae All eukaryotic, multicellular organisms
cell walls made of cellulose
all autotrophic (photosynthesis)
Sexual Reproduction (Alternation of Generations)
Sessile (non-motile)
500,000 + sp.

14. Kingdom Animalia

15. Animalia Eukaryotic Multicellular
Specialized cells that form tissues & organs – such as nerve & muscle
No cell walls
Heterotrophic – ingest food to obtain energy & then digest food
Develop from a zygote
Usually can move
1.2 million +
Sponges, jellyfish, insects, snakes, birds, fish, mammals, etc.
