2. Glossary
Taxonomy: The branch of science that deals with the classification of organisms.
Prokaryotic: Organisms whose Cells that LACK a nucleus
Eukaryotic: Organisms whose Cells that HAVE a nucleus and membrane bound organelles.
Multicellular: Organism made up of more than one cell
Unicellular: Organism made up of ONLY ONE cell
Autotrophic: Organism that makes energy by making its own food (photosynthesis).
Heterotrophic: Organism that obtains energy by eating other organisms.
Asexual reproduction: reproduction that involves one parent-spores, budding, regeneration. “Offspring” is identical to parent.
Sexual Reproduction: reproduction that involves two parents. Fusion of sperm and egg to produce genetically distinct offspring.

3. Hierarchical Classification
Organisms are placed into taxa
Species: Panthera pardus
Genus: Panthera
Family: Felidae
Classification
groups
Order: Carnivora
Class: Mammalia
The taxonomic hierarchy:
Phylum: Chordata
Kingdom: Animalia
Domain: Eukarya
Archaea
Bacteria
The three domains of life
Figure 14.22

4. Some Basics of Taxonomy
Carolus Linnaeus
developed binomial nomenclature, the formal naming system used today
Each species is assigned a two-part scientific name consisting of the Genus and the species
Scientific names are underlined or italicized
Example: Homo sapiens
Upper case
lower case

5. The Three Domain System
Is one alternative to the six-kingdom system
Bacteria
Archaea
Eukarya
Earliest organisms

6. Arranging Life into Kingdoms: A Work in Progress
Arranges life into kingdoms based on specific characteristics
Figure 14.27a

7. The Six Kingdoms Domain: Archae or Bacteria
Kingdom: Archea or Bacteria
Cells: Prokaryotic
Uni-cellular
Autotrophs or Heterotrophs
Reproduction: Asexual and sexual (conjugation)
Examples of Bacteria
E-Coli
Pneumococcus
Salmonella
Cyanobacteria
Examples of Archae:
Halobacterium (salt lovers)
Thermopoteus (hot water lover

8. The Six Kingdoms Domain: Eukaryota Kingdom: Protista Cells: Eukaryotic
Mostly Uni-cellular
Autotrophic or Heterotrophic
Reproduction: Sexual and Asexual
Examples:
Algae (plant-like) – autotrophic
Protozoans (animal-like) – heterotrophic
Slime molds (fungus-like) – multi-cellular

9. The Six Kingdoms Domain: Eukaryota Kingdom Fungi Cells: Eukaryotic
Mostly Multi-cellular
Heterotrophic
Reproduction: spores (asexual and sexual)
Examples
molds, yeasts (uni), mushrooms

10. The Six Kingdoms Domain: Eukaryota Kingdom Plantae Cells: Eukaryotic
Multi-cellular
Autotrophic
Reproduction: Sexual and Asexual
Examples:
Mosses
Ferns
Pines
Flowers
Trees
Grasses
Cactus

11. The Six Kingdoms Domain: Eukaryota Kingdom: Animalia Cells: Eukaryotic
Multi-cellular
Heterotrophic
Reproduction: Sexual
Examples:
Insects
Spiders
Fish
Birds
Amphibians
Mammals
