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.
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?
Lysosomes They are only in plant cells, and Much
like our intestines, lysosomes break down
materials in the cell and get rid of waste.
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!
9
1. Which picture represents an animal cell?
B
A
10
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.
11
2. Which part of the human body is much like the
mitochondria and chloroplast?

• Hint This is how the cell creates energy

12
The answer is
13
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 dont need a vacuole.
• D. Vacuoles get rid of waste and plant cells
  have more waste.

14
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?
16
The answer is plant cells
17
5. Which arrow is pointing to the ROUGH
endoplasmic reticulum on this animal cell?Hint
This is one way the cell makes new materials
18
The answer is B
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!
