&
Objectives:
1. Know the founder of classification.
2. Know the seven levels of classification.
3. Know how to name organisms using scientific names
4. Know how to use a Dichotomous Key to identify organisms.
5. Know the names of the five kingdoms.
6. Know the five main characteristics of each kingdom.
Classification
• The arrangement of organisms into orderly groups based on like physical characteristics.
• Physical characteristics: Observable traits.
(Things that you can see)
Examples: Color, number of legs, wings
(measured)
• The following are not physical
characteristics: can fly, swim, talk, walk
present, size
Taxonomy
The science of identifying, classifying
and naming organisms.
Carolus Linnaeus discovered taxonomy
during the 1700’s.
He tried to classify organisms using
like characteristics.

Organisms are
classified into smaller

Using the seven levels of classification
Naming Organisms
Organisms are normally called by common names. (Ex. Human)
All Organisms also have a
scientific name.
An organism’s scientific name comes
the classification system.
from the Genus and species of
Example: A human’s scientific name is
Homo sapien or
Homo sapien (Italics)
Scientific names are usually Greek or Latin.
Dichotomous Key
• Used as a way of identifying
organisms.
• Descriptive questions are asked about the organisms physical
characteristics, usually with
yes or not answers.
• They can look like a flow chart or a numbered list of
questions.
The Five Kingdoms
All living things (organisms) can
kingdoms:
be placed in one of five
Bacteria (monera)
Protists (Protista)
Fungi
Plants (Plantae)
Animals (Animalia)
Main Characteristics
Kingdom Monera (bacteria)
• One celled organisms (unicellular)
• Contain a cell wall
• Do NOT have a nucleus (Prokaryotic)
• Most do not move on their own
• Obtain energy by feeding off of dead
organisms (decomposers)
Main Characteristics
Kingdom Protista (protists)
• Most are unicellular, some are multicellular (more than one cell)
• Do NOT contain a cell wall
• Do have a nucleus (Eukaryotic)
• Some move on their own
• Some obtain energy by making their
own food (producers), some are
decomposers and other obtain food
(consumers).
Main Characteristics
Kingdom Fungi
• Most are multi-cellular, a few are
unicellular.
• Contain a cell wall
• Do have a nucleus (Eukaryotic)
• Do not move on their own
• Obtain energy by feeding off of dead
organisms (decomposers)
Main Characteristics
Kingdom Plantae (Plants)
• Multi-cellular organisms
• Contain a cell wall
• Do have a nucleus (Eukaryotic)
• Do not move on their own
• Obtain energy by making their own
food (producers)
Main Characteristics
Kingdom Animalia (Animals)
• Multi-cellular organisms
• Do Not contain a cell wall
• Do have a nucleus (Eukaryotic)
• Move on their own from place to
place
• Obtain energy by eating other organisms (consumers)
