TAXONOMY &
CLASSIFICATION
SCIENTIFIC NAMES
• Taxonomy is the science of classifying
organisms and assigning each an official
name
• Early methods described physical
characteristics in great detail
•
Post Oak Tree - “Oak with deeply divided leaves that
have no hairs on the undersides and no teeth around
their leaf edges”
• Our current classification system is based
on the work of Carl Linneaus.
• Binomial Nomenclature- a two word
naming system using the genus and species
names
• (Post Oak - Quercus stellata)
