Activity: Specialized Cells
Directions:
1.
Read the information on the slide and circle if the slide is describing a
UNIcellular organism or one TYPE of cell that is from a MULTIcellular organism.
2.
Circle if the cell is specialized or NOT specialized.
3.
TYPE a short description of why you said it is/is not specialized.
A. Complete this sentence frame to explain why the cell IS specialized:
The ONE job that this cell has is…
B. Copy this sentence to explain why the cell is NOT specialized:
This cell does ALL jobs needed for life.
Is this a unicellular organism or
one type of cell from a
multicellular organism?
From a Multicellular organism

Why/Why not is this a specialized cell?
“The ONE job that this cell has is …”
OR
“This cells does ALL jobs needed for
life.”

Activity: Specialized Cells
Neuron
I am one of millions of nerve cells that live in your body. I am connected to
other neurons in the brain and spinal cord. I take in information from your
five senses and send messages through to the brain and spinal cord.

Activity: Specialized Cells
Macrophage
I am very large and very hungry. I like to eat bacteria and viruses that enter
your bloodstream. I work together with many other white blood cells to
protect your body from disease. My job is to eat the bacteria once the
other white blood cells have caught them

Activity: Specialized Cells
Amoeba
I live in pond water and I eat my food by creating a membrane around it and
letting it come past my cell membrane. I can get as big as 1mm in size. I use
my vacuole to help me move around by taking in and releasing water.

Activity: Specialized Cells
E. Coli
I live in your intestine and help you digest some of the food that you can’t.
Sometimes you accidentally eat me and I make you sick. To prevent my visit
you should wash your hands and cook your food thoroughly.

Activity: Specialized Cells
Epithelial
I am a very flat and smooth cell. I am found in many places in and on your
body. I am able to reproduce quickly. This is helpful because cells like me get
damaged often. When I reproduce I repair the skin or tissues that are
damaged.

Activity: Specialized Cells
Cardiac
I am very strong and I have a branch shape that allows me to connect in
chains with other Cardiac cells. Together, we are able to contract to make
your heart beat. This sends blood throughout your body.

Activity: Specialized Cells
Euglena
I live in pond water and you have to see me with a microscope . I have
chloroplasts and can absorb sunlight to make sugar. I have a flagellum, that
looks like a tail, which I use like a motor to move around.
