Classification of Organisms
I.
A.
Classification
Arrangement in classes or groups
to improve communication
between scientists.
B. Four factors used to classify
1. They have similar structures
2. They have similar behaviors
3. They eat the same kinds of things
4. They have the same chemical make up.
II. Five Kingdoms of Living
Things
 A.
Moneran Kingdom
1. Simple single celled
Example: Bacteria
2. Helpful types
a. Decomposers
b. Yogurt
3. Harmful types
a. Pathogens – cause disease
b Strepthroat
II. Five Kingdoms cont
.
B. The Protist Kingdom
1. Complex , single celled organism
a. Euglenas- make their own food
b. Protozoans – depend on getting food from
other sources.
c. Examples of common
protists are as follows
Trypanosoma use flagellum to move

Here is an Amoeba with its pseudopods
II.
Five Kingdoms cont.
C. The Fungi Kingdom
1. Many celled organisms
2. Depend on others for
food
a. Sprophytes- eat dead things
b. Parasites – attack living tissues
3. Examples of
a. Yeasts

And here is a Mushroom
II.
Five Kingdoms cont

»D. The
Plant
Kingdom
1. Many celled organism

2.
They make their own food.
–a. Process called photosynthesis
–b. Examples:
–Trees, flowers, and grass
E. The Kingdom Animalia
The Animal Kingdom cont.
1. Many Celled Organisms
2. Consume other Organisms for food
3. The Subdivision of this Kingdom
a. Naming Organisms
b. Common names – house cat

Let’s look at how we would scientifically name the
Columbine.

current.

2. Phylum: Coelenterata cont.

1. Food absorbed by inner cell wall
2. Single opening mouth
f. Circulation – water current distributes
gas/food
3. Phylum: Platyhelminthes –
The Flatworms
a.
Parasites live off host

broken.
c.Respiration – Oxygen absorbed through the skin
d. Digestion -
1. Nutrients absorbed into the skin
2. Single opening mouth
e. Circulation – Nutrients/ gas circulated by host
4. Phylum Nematoda - Roundworms
a. Many are parasites / some free - living
b. Respiration – Oxygen absorbed through the skin

cell layer.
2. Complete system
( Two Openings)
D. Circulation - Food / gas absorbed through cells
5. Phylum Annelida The Segmented Worm
