1. The Three Domains 1. Archaea 2. Bacteria 3. Eukarya
All organisms belong to one of three domains, depending on their characteristics. A domain is the broadest taxonomic category. A single domain can contain one or more kingdoms.
1. Archaea
2. Bacteria
3. Eukarya
TAXONOMY: The science of finding, describing, classifying and naming organisms.

2. The Three Domains
1. Archaea: ancient forms of bacteria 2. Bacteria : more advanced forms of bacteria 3. Eukarya: all life forms with eukaryotic cells

3. The Three Domains of Life
Organisms are placed into domains and kingdoms based on their cell type, their ability to make food, and the number of cells in their bodies.
Ability to make food
Ability to reproduce
Heterotrophic or Autotrophic
Asexual or Sexual Reproduction
Cell Type
Number of cells in their body
Prokaryotic or Eukaryotic
Unicellular or Multicellular

4. The Three Domains of Life
Organisms can be:
Prokaryotic – cells that lack a nucleus
Eukaryotic – cells that contain a nucleus
Unicellular – single-celled; made up of one cell
Multicellular – made up of many cells
Autotrophic – can make their own food
Heterotrophic – can not make their own food
Asexual – reproduce with only one organism.
Sexual reproduction – 2 parents are needed for reproduction.

5. The Six Kingdoms of Life
Domain Archaea
(under this tab write this information)
Kingdom Archaebacteria
Characteristics:
1. Known as “ancient bacteria”;
2. They thrive in the most extreme environments on Earth; they are often referred to as “extremophiles”
3. Found in hot springs, very salty water, swamps, and the intestines of cows
4. Unicellular
5. Prokaryotic
6. Small cells
7. Asexual

6. The Three Domains of Life
Domain Bacteria
(write this under the Domain Bacteria tab)
Kingdom Eubacteria
1. They are found everywhere on Earth except extreme environments.
2. Unicellular,
3. Prokaryotic – no nucleus
4. Asexual
5. Example: Bacteria

7. Domain Eukarya Kingdom Fungi eukaryotic most are multicellular
Heterotrophic
Have a Cell Wall
Examples: yeast, molds, mildews, and mushrooms

8. Domain Eukarya Kingdom Protista (Protists)
“the “odds and ends” kingdom;
includes any organism that can not be classified as a animal, plant, or fungus
eukaryotic
some are unicellular, others are multicellular
some are autotrophs, others are heterotrophs
Lives in moist environments.
euglena
amoeba
paramecium

9. Domain Eukarya Kingdom Plantae (plants) Plants multicellular
eukaryotic
autotrophic
most live on land
Plants
multicellular
eukaryotic
autotrophic
most live on land

10. Domain Eukarya Kingdom Animalia ( (Animals – you) multicellular
eukaryotic
heterotrophic
live in diverse environments
