3. Just as cars are classified based on their brand, make, model, and color; plants and animals are classified into different categories based on similarities of structure and evolutionary history.

4. What is Taxonomy? A systematic method of classifying plants and animals. Classification of organisms based on degrees of similarity supposedly representing evolutionary (phylogenetic) relatedness.

5. Importance of Taxonomic System  Taxonomy creates a vivid picture of the existing organic diversity on earth.  Taxonomy provides information that enables scientists to make a reconstruction of the phylogeny of life.  Taxonomy divulges numerous evolutionary phenomena.  Taxonomy supplies classifications which lead to explain branches of biology and paleontology.

6. Past & Present:  Organisms were first classified over 2000 years ago by the Greek philosopher, Aristotle. He grouped animals into land, water, and air dwellers.  He also grouped plants into three categories. These were based on different stems. This classification system became insufficient over time as many new species were discovered.  Common names were no longer effective either because these differed between different locations. (oak tree, goldfish)  Biologists then developed the biological classification system to name, organize, and categorize organisms.  The new classification system is now strongly based on common descent through DNA analysis rather than solely physical similarities of plants and animals.

Family 7. Genus 8. Species Domain was not originally a part of the system, but once scientists discovered that bacteria consist of two distinctly related groups, an 8 th taxonomic rank was added to the top of the hierarchy- domain.

11. Things to Know:  Classification - The process of grouping things based on their similarities  Binomial nomenclature - System of naming organisms based on observable features (two names). Created by Linnaeus  The 3 main characteristics used to classify organisms into domains and kingdoms are: - cell type - their ability to make food, - the number of cells in their bodies Review From Chapter on Cells:  Prokaryote - Organisms whose cells lack a nucleus  Eukaryote - Organisms with cells that contain a nuclei.

12. Domain: Consists of Archaea, Eubacteria, and Eukarya I.Archaea’s Kingdom: Archaebacteria Kingdom II.Eubacteria’s Kingdom: Eubacteria Kingdom III.Eukarya’s Kingdoms: Protista Kingdom Fungi Kingdom Plantae Kingdom Animalia Kingdom

13. Archaebacteria Kingdom (under Archaea Domain) Consists of Organisms: Methanogens, Halophiles, Thermophiles, Psychrophiles Cell Type: Prokaryotic Characteristics: Cell Structures: Cell walls WITHOUT peptidoglycans Number of Cells: Unicellular Mode of Nutrition: Autotroph or heterotroph Eubacteria Kingdom (under Eubacteria Domain) Consists of Organisms: Bacteria, Cyanobacteria(blue-green algae), Actinobacteria Cell Type: Prokaryotic Characteristics: Cell Structures: Cell walls WITH peptidoglycans Number of Cells: unicellular Mode of Nutrition: Autotroph or heterotroph

14. Protista Kingdom (under Eukarya Domain) Organisms: Amoebae, green algae, brown algae, diatoms, euglena, slime molds Cell Type: Eukaryotic Characteristics: Cell Structures: Cell walls of CELLULOSE: some have chloroplasts Number of Cells: Most unicellular, some colonial or multicellular Mode of Nutrition: Autotroph or heterotroph Fungi Kingdom (under Eukarya Domain) Organisms: Mushrooms, yeast, molds Cell Type: Eukaryotic Characteristics: Cell Structures: Cell walls of CHITIN Number of Cells: some unicellular, MOST MULTICELLULAR Mode of Nutrition: Heterotroph

15. Plantae Kingdom (under Eukarya Domain) Organisms: Mosses, angiosperms (flowering plants), gymnosperms, liverworts, ferns Cell Type: Eukaryotic Characteristics: Cell Structures: Cell walls with CELLULOSE; chloroplasts Number of Cells: MULTICELLULAR Mode of Nutrition: Autotroph Animalia Kingdom (under Eukarya Domain) Organisms: Mammals, amphibians, sponges, insects, worms Cell Type: Eukaryotic Characteristics: Cell Structures: NO Cell walls and NO CHLOROPLASTS Number of Cells: Multicellular Mode of Nutrition: Heterotroph
