1 Classification: Linnaeus and Biological
TSW investigate the process of classification and use a dichotomous key to identify organisms

2 What is classification?
Grouping of organisms according to their characteristics in a logical manner Taxonomy: discipline of classifying organisms & assigning each organism a universally accepted name

3 How can we organize 1,000,000+ organisms?
Taxonomy: deals with describing, classifying, and naming organisms Constantly changing…WHY? We currently have 6 Kingdoms (then divide from there)

4 Linnaeus’s System of Classification
Consists of seven levels Each level is called a TAXON (plural: taxa) Kings Play Cards On Fat Green Stools

5 Taxonomic Categories Kingdom……………………………………..100,000+
Phylum………………………………………….10,000+ Class………….……………………………………1,000+ Order…….…………………………………………..100+ Family.…………………….……………………………50+ Genus……………………………………………………12+ Species……………………………………………………..1

6 Binomial Nomenclature
Uses 2 words to identify an organism 1st word: Genus (capitalized) 2nd word: Species (Lowercase) When printed, must be underlined or italicized Example: Homo sapiens or Homo sapiens

7 A species is a group of organisms that are…
Physically similar Potentially interbreeding Sharing a common gene pool Reproductively isolated Able to produce viable offspring

8 How do new species form? Environmental or genetic changes cause portions of a population to become reproductively isolated from the rest of the group

9 What are the 6 Kingdoms? Archaebacteria Eubacteria Protista Plantae
Fungi Animalia

10 Which kingdoms have organisms that can reproduce sexually & asexually?
ALL 6 Kingdoms!

11 Archaebacteria Example: Deep Sea Hydrothermal Bacteria

12 Eubacteria Example: Streptococcus Escherichia coli

13 Protista Examples: Amoeba Paramecium Slime molds Giant Kelp

14 Plantae Example: Mosses Ferns Flowering Plants

15 Fungi Example: Mushrooms Yeast

16 Animalia Examples: Sponges Worms Insects Fishes Mammals
