Is this what E. coli would look like under
a microscope?
This is a better idea of what it would
look like.

Introduction
• Which of these organisms do you have the
most in common with?
3
Classification
Organisms are divided into groups known as
Domains and Kingdoms.
What do you think would be the best way
to classify organisms into groups?
(answers will vary)
4
More about Classification
The classification into Domains and Kingdoms
is mainly based on:
•Cell structure
•How they obtain energy
•How they reproduce

Algae
Kingdom Protista
• Made up of one or more cells; each cell
has a nucleus (Eukaryote)
• Found in freshwater and marine
environments
• Some are mobile and have flagella
• Makes its own food by photosynthesis and
absorbs nutrients from its environment
• Reproduces asexually and sexually
Paramecium
Kingdom Protista
• Made up of one cell; has a nucleus
(Eukaryote)
• Found in freshwater environments,
commonly in scums
• Mobile: uses cilia for locomotion
• Uses cilia to sweep up food found in its
environment
• Reproduces asexually and sexually
Destroying angel
Kingdom Fungi
• Made up of many cells; each cell has at
least one nucleus (Eukaryote)
• Found on land, usually near trees or
shrubs
• Immobile
• Absorbs nutrients from its environment
• Reproduces asexually and sexually
• Extremely poisonous
Yeast
Kingdom Fungi
• Made up of one cell that has a nucleus
(Eukaryote)
• Found on land and in freshwater and
marine environments
• Immobile
• Absorbs nutrients from its environment
• Reproduces asexually or sexually
• Used in baking bread and brewing beer
Cactus
Kingdom Plantae
• Made up of many different kinds of cells;
each cell has a nucleus and a cell wall
(Eukaryote)
• Found on land, in desert environments
• Immobile
• Makes its own food by photosynthesis
• Reproduces sexually
Elodea
Kingdom Plantae
• Made up of many different kinds of cells;
each cell has a nucleus and a cell wall
(Eukaryote)
• Found underwater, throughout North
America
• Immobile
• Makes its own food by photosynthesis
• Reproduces sexually
Bonobo
Kingdom Animalia
• Made up of many different kinds of cells;
each cell has a nucleus (Eukaryote)
• Found on land, in rainforests in Africa
• Moves by walking upright and on all fours
• Eats fruits, leaves, and small animals
found in its environment
• Reproduces sexually
Barnacle
Kingdom Animalia
• Made up of many different kinds of cells;
each cell has a nucleus (Eukaryote)
• Found in marine environments; attached to
hard substances
• Moves by swimming when young; adults are
immobile
• Feeds on plankton found in its environment
• Reproduces sexually
L. acidophilus
Domain Bacteria

common in human and animal
intestines
• Moves by using a flagellum
• Metabolizes sugars found in its
environment
• Reproduces asexually
E. coli
Domain Bacteria
• Made up of one cell that has a cell wall
but not a nucleus (Prokaryote)
• Found in many different environments;
common in human and animal
intestines
• Moves by using a flagellum

environment
• Reproduces asexually
Halobacteria
•Made
Domain Archaea
up of one cell without a
nucleus (Prokaryote)
•Found in salt water environments
•Moves by using a flagellum
•Uses sunlight for energy
•Reproduces asexually
Ferroplasma
•Made
Domain Archaea
up of one cell, without a
nucleus (Prokaryote)
