Classification
Lions, and Tigers, and Bears, and
Bacteria, and Archaebacteria, and
everything else….Oh my!
Classification
• Classification - basic method
humans use to organize the
living world.
• Easy and time-saving
• Tells us about organism
interrelationships
• Allows information to cross
language and cultural barriers
• Various fields depend on the
correct identification of diseasecausing organisms and insect pests
Types of Classification
smallest
• Organisms are
grouped into smaller
and smaller groups
based on their
differences and
similarities.
largest
Domains
• Three Domains:
• Archaea
• Bacteria
• Eukarya
Domains
• What’s the difference between the
domains?
• Eukaryotic cells versus Prokaryotic cells
• Domain Eukarya have Eukaryotic cells
(Nucleus!)
• Domains Archaea and Bacteria have
Prokaryotic cells (No Nucleus!)
Kingdoms
• Each Domain is broken
into Kingdoms.

How does classification
work?
Life
• All prokaryotic organisms are
in Domain Archaea or
Domain Bacteria
Domain

Eubacteria
Kingdom
Archaebacteria
• Organisms are divided
between them by the slight
differences in the organisms’
cell structure.
How does classification
work?
• Sorting eukaryotic
organisms into
Kingdoms:
• prokaryotic or eukaryotic
• unicellular or
multicellular
• autotrophic or
heterotrophic
• mode of reproduction

So now what?
• Now it’s your turn!
• Break into pairs.
• Each pair send up a representative to
collect a plastic organism bag and a
Kingdom Answer Key.
• When you return to your desk, WRITE
YOUR NAMES on the Kingdom Answer
Key.
• Listen for more instructions.
