We must think of cells as tiny living
creatures.

Each cell exhibits the characteristics of
life.

<image>
They require materials such as water and
nutrients to survive.

<image>
They also rely on gas exchange whether it
is taking in oxygen or carbon dioxide from
the atmosphere.

<image>
But, once they take in all these materials,
how do they get rid of them, or “take out
the trash?”

Cells have specialized organelles that
function as storage facilities, and take
care of cellular waste.

<image>
All the organelles in a cell work together in
order to store and deposit waste.

Remember…the nucleus of the cell is the
control center, so it works with other
organelles such as vacuoles and
lysosomes to initiate some cell functions.

Ask yourself, where does your body store
food energy for later use?

If you answered body fat, you are correct!
<image>
Cells also store food energy in organelles
called vacuoles. These vacuoles act as
storage facilities, storing materials
necessary for the cell.
http://pixabay.com/en/lockers-schoolprotect-store-94959/
<image>
Vacuoles either store the food as it came
into the cell, or they store it after it has
been converted into useful molecules for
quick use.

Once materials are stored, how does the
cell know when to release them?
http://pixabay.com/en/preparations-jarsjam-natural-food-428104/
<image>
Just like when you are thirsty, your brain
sends chemical signals to your body to
prompt you to go and find water.
http://pixabay.com/en/water-glasstransparent-369850/
<image>
In a cell, the nucleus sends a chemical
signal to the vacuole that contains water
molecules.
http://pixabay.com/en/water-fountainwater-basin-435847/
<image>
After the signal is received, the water is
taken from the vacuole and transported to
the area in need via a vesicle. Think of
vesicles as tiny taxi cabs!
http://pixabay.com/en/taxi-cab-taxicab-taxicab-new-york-238478/
Question for Clip C
Stem:
Through which of the following processes
do vacuoles know when to release their
contents into a vesicle?
Answers for Question C
A. A physical signal from the cell
membrane prompts the vacuole.
B. A chemical signal from the area in
need prompts the vacuole to send a
taxi.
C. The vacuole constantly monitors
organelles in the cell and waits for
their signal.
D. A chemical signal from the area in
need is sent to the nucleus, and the
nucleus sends a chemical signal to
the vacuole.

Similar to the way the nucleus
communicates with the vacuole, it also
communicates chemically with lysosomes.

Lysosomes are the organelles that are
responsible for getting rid of cellular
waste, just like a garbage service.
http://pixabay.com/en/man-garbage-baggarbage-people-678326/
<image>
Lysosomes clean up the cell just as you
might clean your room.

Waste within the cell includes things like
digested food and dead organelles.

Question for Clip D
Stem:
Which of the following organelles is
responsible for cleaning up cellular waste
like digested food and dead organelles?
Answers for Question D
A. Nucleus
B. Vacuoles
C. Lysosomes
D. Cell Membrane

Cells take in materials like food, water,
and gases.
http://pixabay.com/en/breakwater-seawave-water-spray-379252/
<image>
Cells have specialized organelles that
store these materials, and remove
byproducts of these materials from the
cell.

Vacuoles act as storage facilities, storing
water and food molecules.

cellular waste from the cell.

Question for Clip E
Stem:
After food is digested in a cell, which of the
following answers best describes what
happens to the food waste?
Answers for Question E
A. Vacuoles take in the food waste,
and the cell becomes polluted with
waste.
B. The organelle that created the
byproducts from the food releases
the waste into the cytoplasm to
permanently float around.
C. Specialized organelles called
lysosomes clean up the cell by
taking the food particles and
depositing them outside the cell
membrane.
D. The digested food is taken in by
another organelle and used until
there is no waste.

In order to survive, cells must take in
molecules such as water.
http://pixabay.com/en/lynx-lynx-lynx-catbig-cat-drink-175968/
<image>
Water diffuses through the cell membrane
and is stored in the cell in an organelle
called the vacuole. Think of vacuoles as
water towers for the cell.
http://pixabay.com/en/water-tower-towerurban-historic-532274/
<image>
Not only can vacuoles store water, but
they can also store other materials such
as food, just like a silo on a farm.

Or a pantry in your kitchen…

Question for Clip F
Stem:
Which of the following answers is most
similar to the function of the cell’s
vacuoles?
Answers for Question F
A. A trash can in your house
B. A car in your driveway
C. A water tower for your town
D. A bed in the bedroom

Materials stored in vacuoles are used by
the other organelles within the cell.
http://pixabay.com/en/preserving-canningpreserves-garden-248030/
<image>
In order for those organelles to receive the
materials they need, they must send
chemical messengers to the cell’s
nucleus.
http://pixabay.com/en/fireworkspyrotechnics-flame-bright-344769/
<image>
The nucleus controls everything in the cell
including the distribution of materials.
http://pixabay.com/en/mixing-desk-mixerslide-control-351478/
<image>
So, once the message is received by the
nucleus, it can send a chemical message
to the vacuole to release the materials into
a vesicle and send them to the organelle.

Question for Clip G
Stem:
Which of the following organelles is
responsible for physically transporting
needed materials from the vacuole to the
other organelles?

Organelles called lysosomes act as the
cleaners of the cell.

<image>
They are responsible for accepting waste
materials, and transporting them to the
outside of the cell.
http://pixabay.com/en/stroller-childrenwalk-dare-502934/
<image>
Lysosomes are also controlled by the
nucleus.

It is easy to remember the function of the
lysosomes if you compare them to
garbage trucks.
