CELLS
The Building Blocks of Life
Students will:
1. Use pictures of animal and plant cells to identify the organelles.
2. Compare/Contrast the organelles and structures of plant and animal
cells.
3. Understand how living organisms depend on cells to carry out the life
functions of:
Extracting energy
Getting rid of waste
Making new materials
4. Understand that organisms could not live without cells

Comparing
Animal and Plant Cell

Plant cells have a cell wall, but
animal cells do not. Both plant
and animal cells have a cell
membrane.

Cells and cell organelles keep us alive!
Cell organelles can be compared to organs in our own bodies. Would you be
able to live without your brain, lungs, stomach, skin or your intestines?
Brain
Lungs
Skin
Intestines
Stomach
Place your
mouse over the
name of a body
organ to read
about a cell
organelle just
like it.

organ, click here

Cell organelles can be compared to organs in our own bodies. Would you be
able to live without your brain, lungs, stomach, skin or your intestines?
Cell Membrane
Much like skin, the
cell membrane is
flexible protection
allowing only certain
things in and out.

Cell organelles can be compared to organs in our own bodies. Would you be
able to live without your brain, lungs, stomach, skin or your intestines?
Mitochondria and
Chloroplasts
They allow the cell to
breathe (respiration)
and gives the cell
energy, just like our
lungs do for us.

Cell organelles can be compared to organs in our own bodies. Would you be
able to live without your brain, lungs, stomach, skin or your intestines?
Nucleus
Much like the brain,
this is the control
center and tells the
cell what to do.
How else would
you know how
breathe when you
are not “thinking”
about it?

Cell organelles can be compared to organs in our own bodies. Would you be
able to live without your brain, lungs, stomach, skin or your intestines?
Vacuole
Much like your
stomach, the
vacuole stores
water and other
materials for the
cell until it is ready
to be used.

Cell organelles can be compared to organs in our own bodies. Would you be
able to live without your brain, lungs, stomach, skin or your intestines?
Lysosomes
They are only in
plant cells, and
Much like our
intestines,
lysosomes break
down materials
in the cell and
get rid of waste.
QUIZ
CLICK TO ENTER
1. Click on the picture that represents an animal
cell.
Beginning
of Quiz
YES!
Think of the cell membrane of an
animal call like a plastic bag. It
holds everything inside of the cell,
yet it is flexible with tiny holes
which allow some things to pass in
and out.
Next
Try again
This is a picture of a
plant cell. Plant cells are
square and rigid with cell
walls. Animal cells are
round and flexible with
NO cell wall.

Question
2. Which part of the human body is much like the
mitochondria and chloroplast?
Hint: This is how the cell creates energy
Brain
Lungs
Stomach
Intestines
Beginning
of Quiz
YES!
Mitochondria and
Chloroplasts
Allows the cell to
breathe (respiration)
and gives the cell
energy, just like our
lungs do for us.

3. Why is the vacuole so much larger in plant cells
than in animal cells?
A. It is what makes plants green.
B. It holds lots of water for the plant and gives the
plant structure.
C. Animal cells don’t need a vacuole.
D. Vacuoles get rid of waste and plant cells have
more waste.
Beginning
of Quiz
Try again
Vacuole does not
get rid of waste,
the lysosome
does
Lysosomes
They are only in
plant cells, and
Much like our
intestines,
lysosomes break
down materials
in the cell and
get rid of waste.
Back to
Question
YES!
Animal cells do have
vacuoles, but the
Vacuole in the plant cell
is much larger. It holds
water, food and
sometimes waste to
protect the rest of the
cell. The large size of
the vacuole also gives
the plant its structure,
which is why a plant
will get droopy if it
needs water.

4. These images come from the same type of cell,
but what kind of cell?
Click to choose:
Plant Cell
Beginning
of Quiz
Animal Cell
Try again
This image is not a picture
of animal cells. Animal cells
are more round and flexible
with thin membranes.

microscope

5. Which arrow is pointing to the ROUGH
endoplasmic reticulum on this animal cell?
Hint: This is one way the cell makes new materials
A
Beginning
of Quiz
B
Try again
A is pointing to the
SMOOTH endoplasmic
reticulum. It is considered
smooth because it does
not have ribosomes
A
attached to it.
Back to
Question
B
YES!
B
A
B is pointing to the
ROUGH endoplasmic
reticulum. You can tell
because it has little
black dots representing
the robosomes that are
attached to it.
The ribosomes create
proteins and the ER
processes them.

THE END
Wrap it up:
Animal and plant cells have many organelles, some of the same and a few that are different.
In any cell, organelles help with basic life functions:
making energy (mitochondria and chloroplasts)
getting rid of waste (lysosomes)
making new materials (ribosomes make proteins)
Life CANNOT live without cells or cell organelles!
