1. Diversity of Organisms and Classification

2. Take these slides of notes in your Spiral Notebook

3. Essential Vocabulary DNA Prokaryotic: a cell that lacks a nucleus
Eukaryotic: a cell that has a nucleus and other complex structures
Feeding
Autotrophic: an organism that makes it’s own food from solar energy or chemicals
Heterotrophic: an organism that must eat other organisms to obtain it’s energy.

4. Classification of Organisms
All organisms can be classified and named according to this system; based on shared traits and a common origin
Kingdom
Phylum / Division
Class
Order
Family
Genus
Species
King
Phillip
Came
Over
For
Green
Soup

5. Five Kingdom System
Bacteria
Protists
Fungi
Plants
Animals

6. Finding Order in Diversity
Why Classify?
To study the diversity of life
To organize and name organisms
Why give scientific names?
Common names are misleading
jellyfish
silverfish
star fish
None of these animals are fish!

7. Bacteria Kingdom Unicellular, microscopic Motile (Move) No nucleus
Prokaryotic
No chlorophyll
Decomposers (Saprophytic)
Parasitic
E. Coli: food poisoning (deadly)
Normally found in intestines
Beneficial
Lactobacillus: yogurt and cheese

8. Protist kingdom Unicellular; microscopic Nucleus present
Eukaryotic
Autotrophic or heterotrophic
Classified by how they move
Plant like: Phytoplankton
Provide 90% of worlds oxygen
Animal like: Zooplankton
Their remains are used in cleansers such as toothpaste and comet

9. Fungus kingdom Eukaryotic Non-motile (don’t move)
No root, stem and leaf
No chlorophyll
Decomposers
Saprophytic or parasitic
Reproduce by forming spores
Most are Multicellular: mushrooms, bread mold etc..
Unicellular: yeasts

10. Plant Kingdom Eukaryotic Non-motile (don’t move)
Most plants contains pigments (chlorophyll) for photosynthesis
Autotrophic
Can be divided into two groups:
Non-flowering plants
Flowering plants

11. Animal Kingdom Eukaryotic
Divided into two groups according to the presence or absence of backbone:
Invertebrates : without backbone
Sponges, Cnidarians, Flatworms, Round worms, Mollusks, Segmented Worms, Arthropods, Echinoderms,
Vertebrates : with backbone
Fish, Amphibians, Reptiles, Birds, Mammals
