Title: CLASSIFICATION


1
CLASSIFICATION
  • How We Group Organisms
  • Page 22 26.

2
CLASSIFICATION
  • methods of grouping things according to
    similarities or differences.
  • Ex. by size, color, age, etc.

3
Classifying organisms is called taxonomy.
  • - started by Aristotle in 350 BC.
  • Many disagreements about the groupings
  • if they live in the air?
  • if they live in the sea?
  • if they live on land?

Where to put frogs? Geese?
4
Todays system is called binomial
nomenclature (two-name naming)
  • Ex. Canis lupus
  • - created by Carolus Linnaeus.

Ex. Canis familiaris
5
Latin was used by scientists and scholars in the
1700s.
  • used today to avoid the confusion of using many
    different languages.
  • Ex. Spanish moss
  • - not Spanish
  • - not moss
  • Tillandia usneoides

6
The Latin names are an organisms genus species
its scientific name.
  • Canis familiaris

Six Kingdom Classification
  • Kingdom Animal
  • are multicellular.
  • can move from place to place.
  • cannot make their own food.

13
  • Kingdom Plant
  • make their own food through photosynthesis.
  • can be multicellular (redwoods) or unicellular
    (plankton)

14
  • Kingdom Fungi
  • - can not make their own food.
  • - absorb food from dead material.
  • Ex. mushrooms, mold, yeast.

15
  • 4) Kingdom Protist
  • -most are unicellular.
  • - some have traits of both plants and animals.

16
Protist Examples
1) Euglena can move but it has chloroplasts
2) Amoeba
17
  • 5) Kingdom Eubacteria
  • Ex. strep, e-coli
  • prokaryotic

18
6) Kingdom Archeabacteria
  • - oldest kingdom the first life on Earth.
  • also prokaryotic

Ex. stromatolites
19
-are more primitive and can survive in harsh
conditions.
20
These kingdoms were formed when Kingdom Monera
