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.

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

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

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.

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

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

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

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

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

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