( Did King Phillip Come Over For Grape Soda?)

the science of giving unique and meaningful names to all the species on Earth

in the mid 1700's developed classification system Systema Naturae

the science of identifying relationships among species

• Bacteria
• Archaea
• Eukarya

• unicellular prokaryoates (lack nucleus)
• heterotrophic (must eat to obtain energy)

• exception: autotrophic (can convert energy)
• use photosynthesis

• unicellular prokaryoates
• extremophiles

• Protista
• Plantae
• Animalia
• Fungi

• diverse group of microorganisms
• unicellular eukaryotic (have nucleus)
• all organisms not in other three kingdoms
• may be autotrophic or heterotrophic

• most multicellular
• have cell walls made of celluose
• typically non-motile
• autotrophic (convert enery through photosysthesis)

• most multicellular
• lack cell walls
• many are capable of movement or movement of body parts, at some time
• heterotrophic (eat to obtain energy)

• multicellular
• typically non moving
• cell wall containing chitin (not cellulose)
• heterotrophic
• many are decomposers (obtain energy by breaking down dead, decaying organisms)

• 1. binomial: genus and species epithet
• 2. unique
• 3. Latinized

• 1. Name after region where found
• 2. Name after person
• 3. Describe a characteristic

• Genus is capitalized, species is not
• italicized if typed
• underlined if hand written

the evolutionary relationshipd among species ; can be represented by a pattern of ancetry and descent

the process of evolution of more than one (usually two) new species from a pre-existing species

depicts pattern of ancestry and descent amoung species

• tips: extant species
• branches: relationships among species
• nodes: where braches meet, common ancestor
• root: oldest shared ancestor
• outgroup: rest of the scies
• polytomy: multiple branches in one node

a specific group that includes a common ancestor and all its descendants

character shared by all members of a clade indentifed by a mark on the branch of tree and desciption

unique character used to identify species using a key
