1. Traveling Through Six Kingdoms
An Introduction to the
Three Domains/
Six Kingdoms of Life
Martin 2011

2. Characteristics of Life
All living things have CELLS:
All living things respond to their environment
All Living things reproduce
All living things use energy
All living things grow and develop
All living things adapt through evolution

3. Classification Groups
Taxon ( taxa-plural) is a category into which related organisms are placed
There is a hierarchy of groups (taxa) from broadest to most specific
Domain, Kingdom, Phylum, Class, Order, Family, Genus, species

4. Hierarchy-Taxonomic Groups
Domain
Kingdom
Phylum (Division – used for plants)
Class
Order
Family
Genus
Species
BROADEST TAXON
Genus and species are the two names used to identify specific organisms in the binomial system of classification. Division is used for plants.
Most Specific

5. Two Types of Cells Prokaryote Simple cells DNA not in nucleus
Eukaryote
Complex cells
DNA in nucleus

6. Prokaryotes: Two Domains, Two Kingdoms
Domain: Archaea Kingdome:Archaebacteria
Domain: Bacteria
Domain: Eubacteria

7. Kingdom Archeabacteria
May be the oldest form of life: lived billion years ago
Most live in extreme places similar to our young Earth: deep sea vents, boiling mud around volcanoes, very salty water (Dead Sea), acidic water
Extremophiles

8. Specs: Unicellular: One cell Prokaryote: DNA is not in a nucleus
Most are Heterotrophs ; a few are Autotrophs
Asexual reproduction

9. Kingdom: Eubacteria Live all around us, in us, and on us
Most are very useful:
Break down waste
Make cheese and yogurt
Make Vitamin K
Make Oxygen
A few cause disease

10. Specs Unicellular : one cell Prokaryote: DNA is not in a nucleus
Most are Heterotroph; a few are Autotrophs
Live under “normal” conditions
Chemical composition is very different form Archeabacteria: Different type of DNA
Asexual reproduction

11. Let’s Look at a Few Shapes
Cocci Bacilli Spirilla
(round) (rod) (spiral)

12. Domain Eukarya : Four Kingdoms
Protista Fungi
Plantae Animalia

13. Kingdom: Protista The “Leftover” Kingdom Plant-like Animal-like
Fungus-like

14. Specs **Unicellular OR Multicellular Eukaryote: DNA is in a nucleus
**Heterotrophs and Autotrophs
**Asexual AND sexual reproduction
**most common

15. A Peep into Kingdom Protista

16. Kingdom Fungi Mushrooms, molds and mildews Most are useful
(food, decomposers)
A few cause disease:
Athlete’s foot
Ringworm
Serious plant diseases

17. Specs Most are Multicellular Eukaryotes: DNA is in a nucleus
ALL are Heterotrophs
Decomposers (dead material)
Parasites (living material)
Asexual AND **Sexual reproduction

18. Kingdom Plantae From tiny Mosses to
giant Redwood trees, all plants use Photosynthesis to obtain energy

19. Specs ALL are Multicellular Eukaryotes: DNA is in a nucleus
ALL are Autotrophs
Contain Chlorophyll (green pigment) for Photosynthesis
**Sexual and asexual reproduction

20. Kingdom Animalia Most animals can MOVE to find food
(at least during part of their life cycle)
All animals must EAT
Carnivore (Animals/ meat)
Herbivore (Plants)
Omnivore (Both plant and animal)
Detritivore (Dead material)
Parasites (Living material)

21. Specs ALL are Multicellular Eukaryotes: DNA is in a nucleus
ALL are Heterotrophs
Most Move
**Sexual and asexual reproduction
