Chloroplast – The plant
organelle which makes
photosynthesis possible.

plant cell then in animal cell

Mitochondria is the only
energy making organelle
in the animal cell.

Lysosomes
Cell organelles keep us alive!
Brain

Intestines
Stomach
Cell organelles keep us alive!
Mitochondria and
Chloroplasts
They allow the cell to
breathe (respiration) and
gives the cell energy, just
like our lungs do for us.
Lysosomes
They are only in plant
cells, and Much like our
intestines, lysosomes
break down materials in
the cell and get rid of
waste.
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 Membrane
Much like skin, the cell membrane is
flexible protection allowing only
certain things in and out.
Vacuole
Much like your stomach, the
vacuole stores water and other
materials for the cell until it is ready
to be used.
QUIZ TIME!
1. Which picture represents
an animal cell?
A
B
The answer is A
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.
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
The answer is…
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.
The answer is B
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?
The answer is plant cells
5. Which arrow is pointing
to the ROUGH endoplasmic
reticulum on this animal
cell?
Hint: This is one way the cell makes new materials
B
A
The answer is B
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.
Great Job!
