Bacteria and Protist
Mrs. Reich’s Science Class
Did you know?
• You can tell bacteria by their shape and
protists (euglena, paramecium, amoeba), by
the way they move and gather food.

Single Celled Organisms
• Bacteria are organisms that are classified into
the Moneran Kingdom. They are classified by
their body shapes.

Protist
• Protists are organisms that
are classified into the
Kingdom Protista.
Although there is a lot of
variety within the protists,
they do share some
common characteristics.
Protist
• Protists are usually one celled organisms that
live in all moist environments. They vary in the
way they obtain food and move. Examples of
protists include euglena, paramecium, and
amoeba.

Euglena
• A Protist with Flagella
• These protists move pulling themselves with long
whip like structure called flagella.
• These protists can have one or more flagella that
help them move.
• The euglena is unique in that it has
characteristics of both a plant and an animal, it
contains chloroplasts that photosynthesize and
also can consume other organisms as well.

Paramecium
• A Protist with Cilia
• These protists move by beating tiny hair-like
structures called cilia.
• The cilia act as tiny oars that allow the protist
to move through its watery environment.
• The cilia also move and help to capture food
directing in toward a groove that functions like
a mouth.

Amoeba
• A Protist with Pseudopods
• These protists move by extending their bodies
forward and then pulling the rest of their
bodies forward as well.
• The finger-like structures that they project
forward are called pseudopods (false foot like
a snail).
• The pseudopods are also used to trap food.
