Transcript Hierarchical Structure of the Classification of Organisms

Hierarchical Structure of the
Classification of Organisms
Classification
• Taxonomy-study of how
scientists classify organisms
• Modern classification system
uses a series of levels based on
structures of the organisms
• The more classification levels an
organism shares, the more
characteristics they have in
common
Levels of Classification
Kingdoms
• 5 kingdoms-Monera,
Protists, Fungi, Plants,
Animals
• Organisms are place in
kingdoms based on
their ability to make
food and the number of
cells in their body
Levels of Classification
Phylum (pl. phyla)
• In the plant kingdom,
phyla are sometimes
referred to as divisions.
• Plants are divided into
vascular and nonvascular.
• There are 35 phyla in
the animal kingdom.
• These are divided into
vertebrate and
invertebrate.
Levels of Classification
Class, Order, Family
• These levels become
even more specific.
• They include fewer
organisms that have
more in common as
they go down the
levels.
Genus
• Contains closely related organisms
• Is used as the first word in an organisms
scientific name
Species
• Consist of organism of same type
• Are able to breed and produce young of the
same kind
• Species used as second word in organisms
scientific name.
Scientific Name
• Name of organism
made up of genus
and species.
• Written in italics
