1. Unit #3 Classification T axonomy
Science dealing with the classification
of organisms
Biologists use classification to organize living things into groups so that the organisms are easier to study.

2. These beetles belong to a large insect collection in a natural history museum. They have been classified according to characteristics they share. Observing What characteristics may have been used to group these beetles?

3. Organisms Classified by:
Structural Similarities
Biochemical Similarities
Cytological Similarities
Embryological Similarities
Behavioral Similarities
Fossil Record

4. Basic Classification Groups
Kingdom
(most general)
Phylum
Class
Order
Family
Genus
Species
(most specific)
Species
Organisms that can mate and
produce fertile offspring

5. LINNAEAN CLASSIFICATION OF HUMANS
Kingdom:   Animalia     Phylum:   Chordata (animals with back bones)         Class:   Mammalia (with hair, females produce milk)           Order:   Primates (apes, monkeys)
Family:   Hominidae (with extinct neanderthal)
                   Genus:   Homo (Same)                          Species:   sapiens (Man)
You see, at every step down the classification ladder, the thing that we are is narrowed down. At first we're just animals. Then the phylum grouping separates us from all animals without backbones, such as sponges, insects, and worms. On down the ladder we go until we land at the species, and at that point we know that we're just talking about one kind of animal, and that animal is us.

6. Five Kingdom System
Animal
Plant
Protista
Monera
Fungi

7. Animal Kingdom
Multicellular
Heterotrophic
Eukaryotes

8. Plant Kingdom
Multicellular
Photosynthetic
Autotrophic

9. Protista Unicellular Eukaryotic Cells (have membrane bound organelles)
Examples: paramecium, amoeba, euglena

10. Monera Unicellular Prokaryotic Cells (no membrane bound organelles)
Examples: bacteria, blue green algae

11. Fungi Most multicellular (except yeast)
Have cell walls, but not chloroplasts
Absorbs nutrients from environment
(heterotrophic)
Examples: yeast, bread mold, mushrooms

12. Nomenclature Examples: Felis domesticus Method of naming an organism
Felis leo
Binomial System
Felis tigeris
Canis lupis
Developed by Carl Linnaeus
Canis familiaris
Rules
Homo erectus
Genus and species name make up
scientific name
Homo sapien
Names usually in latin
Genus is capitalized, species lower case
Name is either italicized or
underlined separately
