1. Classification and Biodiversity

2. About _1.5 million___ kinds of living organisms are known today and each year thousands more are identified.
Some experts believe there are as many ___10 million_ different kinds of organisms.

3. Taxonomy:
Classification and naming of living things.

4. Classification Systems:
How is a grocery store classified/ organized?

5. Early classification:
Aristotle:
Classified organisms by how they moved.
Fly
Walk
Swim
Problems?

6. John Ray: First to use the term Species.
Classified based on structural similarities

7. Carolus Linnaeus: Father of modern taxonomy.
Developed naming system of “binomial nomenclature”

8. Classification Categories
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Primates
Family: Hominidae
Genus: Homo
Species: Sapiens

11. Naming organisms
Nomenclature = naming organisms

12. Common name vs. scientific name
There may be many common names for one organism.
Puma, cougar, mountain lion
Only one scientific name.
Felis concolor

14. Binomial Nomenclature
Hedera helix or Hedera helix
Italicize or underline scientific name
Hedera = genus
helix = species

16. Characteristics of the 6 kingdoms
Monera = bacteria
Cell type = prokaryotic
Body form = mostly unicellular

17. Locomotion: some have flagella
How they get energy:
Photosynthesis
Absorption
Chemosynthesis
No nervous system
Locomotion: some have flagella

18. Protista: Cell Type: Eukaryotic Body Form: Mostly unicellular
Energy: Some photosynthesis, some respiration/absorption
No nervous system
Locomotion:
Flagella: whip like tail
Cilia: tiny hairs
Pseudopods: fake feet/ oozing cytoplasm

19. Fungi Cell type: Eukaryotic Body form: mostly multi-cellular
Energy from decomposition/absorption
No nervous system
No locomotion

20. Plantae Cell type: eukaryotic Body form: multi-cellular
Energy: photosynthesis
No nervous system
Little locomotion

21. Animalia Cell type: eukaryotic Body form: multi-cellular
Energy: cell respiration/ingestion
Yes, have nervous system
Yes, locomotion… walk, swim, fly…

22. Monera Bacteria is the common name for members of this kingdom.
Where can bacteria be found? Everywhere!

23. Bacteria shapes
1. Round (cocci)
2. Rod-shaped (bacillus)
3. Sprial

24. Two groups of bacteria 1. Archaebacteria: ancient bacteria
Adapted to unusual and/or extreme conditions, such as very hot, very salty, or no-oxygen environments. Have several different cellular chemistries from Monera
2. Eubacteria (monera): true bacteria… most bacteria are this type

25. Examples of bacteria and good things bacteria do

28. Animal like Protists
Stentor
Vorticella
Paramecium
Amoeba

29. Plant like protists Algae… green, red, brown Spirogyra Volvox Diatoms
Euglena

30. Fungus-like protists
Slime-molds

31. Watch movie

35. Fungi

37. Plants
Bryophyta: mosses
Tracheophyta: plants with vessels
