Written in italics. First word is
capitalized and the second is not. Homo

Underline to show italics.

Genus
Classification grouping that contains similar,
closely related organisms
Species
Group of similar organisms that can mate with
each other and produce offspring that can also
mate and Reproduce.

Most biologists classify organisms into 8
levels.

Bacteria
Ancient Found in Extreme Environments Unicellular
Prokaryotes/no nucleus
Found everywhere Autotrophs Heterotrophs Prokary
otes---lack nucleus
Found Everywhere Autotrophs Heterotrophs Eukaryo
tes---Nucleus
Placed into domains and kingdoms based on cell
type, ability to make food, number of cells in
their bodies.

Dense area in a cell that contains nucleic
acids---chemical instructions that direct cells
activities
Nucleus
Dense area in cell containing nucleic
acids---Chemical instructions that directs cells
activities.
Prokaryotes---cells with no nucleus
Eukaryotes---Cells with Nucleus

Domain Eukarya
Eukaryotic organism---cannot be classified as
animal, plant or fungus---most unicellular---few
multicellularsome autotrophs other heterotrophs.
Protists
Fungi
Multicellular eukaryotes. All heterotrophs
Plants
Multicellular eukaryotesmost live on
land----autotrophs---provide food for heterotrophs
Animals
Multicellular eukaryoteslive everywhere---hetertr
ophs
