Taxonomy
Classification of Living Organisms

2. Taxonomy
Taxonomy- The branch of science related to the classification of living organisms
Organisms in the same category have similar traits.
Domains and Kingdoms will have the greatest number of species with the most general similarity in traits
Organisms that are in the same genus will share many traits and are closely related
Domain
Have the students draw the graphic organizer into their journals

3. Taxonomy
Species name- Scientists name species by combining the genus and species.
The genus is capitalized and the species is not. Both are italicized.
Example- The genus for humans is Homo and the species is Sapiens. Homo sapiens or H. sapiens are acceptable.
The species name for a Tiger
Is Panthera tigris or P. tigris
Panthera – Genus
tigris- species
Have the students draw the graphic organizer into their journals

4. Domains of Life
The most general category. All of life is categorized into 3 Domains:
Archaea Bacteria Eukarya

5. Archaea
Prokaryotic Cells that have no nucleus or membrane bound organelles
Many are extremophiles that live in extreme environments
Single Cell Organisms
Likely the among the 1st forms of life

6. Bacteria
Prokaryotic Cells that have no nucleus or membrane bound organelles
Single Cell Organisms
First forms of life
Different than Archaea because cell walls are made of a different bio-molecule

7. Eukarya
Eukaryotic cells that have membrane bound nucleus and membrane bound organelles
More complex cells that evolved after prokaryotic cells
Organisms in this Domain are single cell and multi-cellular

8. Eukarya Kingdoms Eukaryotes are divided into 4 Kingdoms
Protists Fungi Animalia Plantae

9. Protists
Protista are simple, predominately unicellular eukaryotic organisms.
Examples includes slime molds, euglenoids, algae, and protozoans.
Some use photosynthesis (autotrophs) and some consume their food (heterotrophs)
More complex than Archaea and Bacteria because they are Eukaryotic cells that have a nucleus.

10. Fungi
Fungi do not carry out photosynthesis and obtain nutrients through absorption.
Examples include sac fungi, club fungi, yeasts, and molds.
Produce spores and are major decomposers

11. Animalia
Animals are multi-cellular organisms composed of eukaryotic cells.
The cells are organized into tissues and lack cell walls.
Heterotrophic-They do not carry out photosynthesis and obtain nutrients primarily by ingestion.
Examples include sponges, worms, insects, and vertebrates.

12. Plantae
Plants are multicellular organisms composed of eukaryotic cells.
The cells are organized into tissues and have cell walls.
Autotrophic-They obtain nutrients by photosynthesis.
Examples include mosses, ferns, conifers, and flowering plants.
