2. Classification of Living Things

3. Alpaca

4. Classification..??

5. Classification System to organize life Classification System
Genus = closely related species
Family = closely related genera

6. Organization of Life Cell Tissue Organ Organ System Organism
Population
Community
Ecosystem
biosphere
Smallest Level
Largest Level

9. Biological Information
DNA (deoxyribonucleic acid)
Recipe for structure & function
Material of heredity

10. Methods of Classification
Common ancestry is basis for classification
Taxonomy = science of classifying organisms
Systematics
Study of diversity of organisms
Based on evolutionary relationships

11. Three Main Domains of Life
Archaea
Bacteria
Eukarya

12. Cell Types of Organisms
Prokaryote (Archaea and Bacteria)
No membrane bound organelles
Genetic material found in a nucleoid
Eukaryote
Membrane bound organelles
Genetic material in a nucleus

13. Archaea Originally thought to be bacteria Live in extreme habitats
Do not cause disease
Prokaryotic
Unicellular

14. Bacteria Found nearly everywhere Some cause disease Prokaryotic
Unicellular

15. Eukarya Unicellular or Multicellular Eukaryotic cells
Divided into at least four kingdoms
Protista
Fungi
Plantae
Animalia

16. Kingdom Protista Mostly single cell organisms
May actually be up to 20 kingdoms
Gave rise to other eukaryotes
Paramecium
Brown algae
amoeba

17. Kingdom Fungi Most are multicellular Absorptive heterotrophs
Most are saprophites
Mosses a small green fungi

18. Kingdom Plantae
Multicellular
Photosynthetic autotrophs

19. Kingdom Animalia
Multicellular
Heterotrophs

22. How can we classify our own living things??
Linnaeus (1750’s) used a two-part naming system from Latin. (Dog = Canis familiaris)
Binomial Nomenclature = a two-part name
1. Genus = first part of the name (Capitalized)
(Groups similar, related organisms)
2. Species = second part of the name. (Lowercase)
(Groups similar organisms that can mate and produce fertile offspring)

23. Classifying Your Own House
Worlds (Earth)
Continents (North American)
Countries (America)
States (Louisiana)
Parishes (St. Tammany) Cities (Covington
Neighborhoods (????…) Streets ( ???…) Houses (???…)

24. Seven Levels of Creature Classification:
Kingdom – Phylum – Class – Order – Family – Genus – Species –
“Kingdom” is the biggest and broadest.
Each kingdom contains phyla – each phyla contains classes, etc.
The more levels that two organisms share, the more characteristics they have in common.

28. Binomial nomenclature
Binomial nomenclature
Genus capitalized
species not capitalized
