1. THE SIX KINGDOMS OF LIFE

2. Domains of Life oldest domain, organisms in the Kingdom Eubacteria
2. Archaea:
includes organisms in the Kingdom Archaebacteria.
3. Eukarya:
contains all four of the eukaryotic kingdoms:
Protista, Fungi, Plantae, Animalia.

3. Domains of Life

4. Classification
Living things are organized into large groups called kingdoms based on the following characteristics:
Cell Type: prokaryotes or eukaryotes
Cell Walls: absence or presence
Body Type: unicellular or multicellular
Nutrition: Autotrophic (makes own food) or heterotrophic(must consume other organisms)
Reproduction: Asexual or Sexual

5. The six kingdoms are:
Eubacteria
Archaebacteria
Protista
Fungi
Plantae
Animalia

6. Eubacteria All bacteria & prokaryotes Found almost everywhere
(fresh water, salt water, land, inside organisms)
All have cell wall (for protection)
Some autotrophic,
some heterotrophic
Reproduce only asexually (by mitosis)
Some decomposers (recycle nutrients)

7. Eubacteria -- Examples
Decomposers
Cyanobacteria (Produce oxygen)
Pathogens (cause disease)
Nitrogen-fixing bacteria
Streptococcus

8. HUMAN DISEASES Caused by bacteria: Strep throat Meningitis
Tuberculosis
Tetanus
Lyme disease
Caused by viruses:
Common cold
Influenza
AIDS
Chicken pox
Hepatitus B
West Nile Virus

9. Archaebacteria All prokaryotes All unicellular All have cell wall
Some autotrohic,
some heterotrophic
Reproduce only asexually (by mitosis)
Live in ordinary and extreme environments (hot springs, salty lakes, no oxygen)

10. Archaebacteria - - - Examples
Thermophiles – “heat loving”
Methanogens (produce methane gas)
Hot springs
Live in the digestive tracts of animals
Halophiles – “salt loving”
Live in the thick mud of swamps
Owens Salt Lake, CA

11. Protista All eukaryotes Some unicellular, some multicellular
Some cell wall, some no cell wall
Some autotrophic, some heterotrophic
Reproduce asexually(mitosis) & sexually(meiosis)

12. Protista -- Examples
Algae
Amoeba
Paramecium
Seaweed

13. Fungi All eukaryotes All multicellular; except Yeast (unicellular)
All have cell walls made of chitin
All heterotrophic
All decomposers
Reproduce asexually & sexually(by spores)

14. Fungi reproduce asexually
& sexually by spores

15. The cells of fungi consists of long filaments called hyphae.

16. Extra-Cellular Digestion
Digestion outside
the organism
Hyphae absorb
nutrients
Hyphae secrete
enzymes
Digestion
(enzymes breakdown “food”)

17. Fungi - Examples
Puffballs
Mushrooms
Shelf fungi
Jelly fungi
Yeast

18. Some fungi are parasites:

19. Plantae All eukaryotes All multicellular (except green algae)
Cell walls made of cellulose
All autotrophic
Reproduce sexually

20. Examples of Plants Green algae Ferns Mosses Pine trees
Flowering plants

21. Animalia All eukaryotes All multicellular No cell wall
All heterotrophic
Reproduce sexually
