The Classification System

The Classification System

• An Interactive PowerPoint Presentation by Stacey
  Podolsky

2
The Classification System

• Why do scientists classify?
• All living organisms have characteristics which
  distinguish them from nonliving objects
• Scientists organize living things into groups so
  that organisms are easier to study

3
There Are Seven Levels of Classification

• Kingdom
• Phylum
• Class
• Order
• Family
• Genus
• Species

4
The Five KingdomsThe broadest level of
organization
5
Monera

• Prokaryotes
• Cells lack a nucleus
• Absorbs its own food
• Some form chains or mats
• Bacteria, blue-green algae, and spirochetes
• Over 10,000 known species

6
Monera

• Eubacteria and Archaebacteria
• A growing number of researchers now divide this
  kingdom into 2 separate kingdoms
• Eubacteria
• The true bacteria
• Autotrophic and heterotrophic
• Can cause strep throat, used to produce yogurt,
  vitamins, etc.
• Archaebacteria
• Autotrophic and heterotrophic
• Live in hot springs, on the ocean floor, salty
  water, your intestines

7
Video 1- Eubacteria

• E.coli

8
Protists

• Its members are very different from each other
• Can be autotrophic or heterotrophic
• Most are unicellular
• protozoa
• some are multicellular
• Seaweed
• Eukaryotic
• Its cells contain a nucleus

9
Fungi

• Multicellular Eukaryotes
• Mushrooms
• Mold
• Mildew
• Unicellular Eukaryotes
• yeast

10
Plantae

• Multicellular eukaryotes
• Autotrophs
• Photosynthetic
• They make their own food
• Mosses, ferns, woody and non-woody flowering
  plants

11
Animalia

• All are multicellular eukaryotes
• Heterotrophs
• They have their own means of locomotion

12
Dog Classification

• Kingdom
• Animalia
• Phylum
• Groups of classes
• Chordata
• Class
• Groups of orders
• Mammalia
• Order
• Groups of families
• Carnivora

13
Dog Classification cont.

• Family
• Groups of species
• Canidae
• Genus
• Groups of closely related species
• Canis
• Species
• Groups of related organisms
• Familiaris

• Kingdom- the broadest of all levels
• Phylum- groups of classes
• Class- groups of orders
• Order- groups of families
• Family- groups of species
• Genus- groups of closely related species
• Species- groups of related organisms
