Why?

taxonomy

- grouping things based on their similarities

Biologists classify because it is easier to study organisms.

Classification System

- scientific study of how living things are classified

Carolus Linnaeus

Swedish botanist, physician, and zoologist who created a biological naming system consisting of two Latin names

binomial nomenclature

- It is a two part scientific name made up of Latin words - the first word being the Genus and the second being the species.

Genus - first part of the name - the group (always capitalized)Example: The group the house cat belongs to is Felis

species - second part of the name - divides the group or genus A species is also a group of closely related organisms that can produce fertile offspring.

Example: The species of the house cat is domesticusFYI: Cats belong to the family felidae (Families have a female Latin ending.) House cat = Felis domesticus, Lion = Panthera leo, Tiger = Panthera tigris, Mountain lion = Puma concolor, Cheetah = Acinonyx jubatus, Bobcat = Lynx rufus,

Seven levels of classification

Organisms are grouped by characteristics, not necessarily by where they live.

Classification starts with the largest characteristics and works down to the species.

Classification System

Kingdom - phylum - class - order - family - Genus - species

King Phillip came over for good soup.

Six kingdoms 1. archaebacteria 2. eubacteria 3. protists 4. fungi 5. plants 6. animals

unicellular - Organism is only one cell.

multicellular - Organism is made up of many cells.

prokaryote - Organism without nucleus

eukaryote - Organism with nucleus

heterotroph - Organism can’t make its own food.Example: eats other organisms

autotroph - Organism makes its own food using light or chemicals

Two ways

photosynthesis - Plants make sugar with carbon dioxide, water, and sunlight.Example: CO2 + H2O + sunlight = C6H12O6 (sugar)

chemosynthesis - Bacteria make sugar with carbon dioxide, water, and hydrogen or methane.

Example: CO2 + H2O + hydrogen or methane = C6H12O6 (sugar)
