Bacteria
and Protists
Academic Standard 7-2.3
Compare the body shapes of bacteria (spiral, coccus, and
bacillus) and the body structures that protists (euglena,
paramecium, amoeba) use for food gathering and
locomotion.

What do I need to know?
Be able to classify bacteria by their
shape and protists (euglena,
paramecium, amoeba) by the way they
move and gather food.
Bacteria are in the kingdom…..
MONERA!!!!
Bacteria are:
One-celled organisms.
Categorized by their shape!!!!!



There are 3 basic bacterial shapes
in the Kingdom Monera
1.
Round – referred to as cocci
2. Rod Shaped- known as bacilli
3. Spiral – corkscrew shaped; known
as spirilla
What do they look like and
where do they live?

How do we know they exist?
We tapped their phone lines!!!

Okay, so we might need them for oil!
Why don’t we destroy them?

Protists
Protists are organisms that are
classified into the kingdom Protista.
There is a lot of variety within the
protists, they do share some common
characteristics.
All protists:
•Have
a nucleus with a nuclear
membrane
•Are usually one-celled
•Live in moist environments
Protists are grouped by the way
they move and obtain food.

Examples: Euglena, Paramecium & Amoeba
EuglenaHave a flagella
Move by pulling themselves with their flagella
characteristics of both plant and animal;
contains chloroplasts that photosynthesize and
can consume other organisms.

2. Protists with Cilia (ex. Paramecium)
 Move by beating (flapping) tiny hairlike structures called cilia
 Cilia act as tiny oars that allow the
protist to move through its watery
environment.
 Cilia also beat and help to capture food
3. Protists with Pseudopods (ex. amoeba)
 Move by extending part of their bodies
forward and then pulling the rest of their
bodies forward
 Pseudopods- (false feet) finger-like
structures that they project forward
 also used to trap food
Observe how they move…
