Agenda
CATALYST!
 EGG LAB!
 ORGANELLE SHOWDOWN!
 TRANSPORT TRASHKETBALL!
 REVIEW GUIDE WORK TIME!
 EXIT QUESTION!

Egg Lab!



An egg is ONE cell!
Underneath the shell is a semi-permeable
membrane… a cell membrane!
If we put this egg into a hypertonic/hypotonic
solution, osmosis will occur.
ORGANELLE SHOWDOWN RULES!
Two teams will line up at the board.
 Each player has to answer the question as
quickly as possible.
 Bring your notecards to line to review as we
play.
 We will keep points and the team with the
most points wins!
 NO HELPING! Automatic 2 point deduction.

SHOWDOWN!
This part of the cell is
selectively permeable
and only allows in
certain things.
SHOWDOWN!
This is an organelle that is
found both in
prokaryotic and
eukaryotic cells.
SHOWDOWN!
This is an organelle that is
found only in plant cells.
SHOWDOWN!
All organelles are found
floating here
SHOWDOWN!
This organelle allows
sunlight to be converted
into sugar.
SHOWDOWN!
This organelle is a
pathway for proteins to
reach the Golgi
apparatus.
SHOWDOWN!
If this organelle were
destroyed, then a cell
could no longer create
ATP (energy)
SHOWDOWN!
This organelle packages
and ships proteins.
SHOWDOWN!
In prokaryotic cells, DNA
is found floating here
SHOWDOWN!
This organelle destroys
old organelles and
cleans up the cell.
SHOWDOWN!
This organelle is the
reason that plant cells
are rectangular
SHOWDOWN!
This organelle contains
the instructions for
creating proteins
SHOWDOWN!
Food and water is stored
inside of this organelle
SHOWDOWN!
2 part question!!
1) Rough ER has this on it.
2) What is the function of
the organelle in number
1?
SHOWDOWN!
2 PART QUESTION!!!
1) This organelle is much
bigger in plants than
animals
2) What is the function of the
answer to #1?
BONUS ROUND!
Each question is
worth 2 points!!
Which of the following is true?




A produces energy
for the cell
D holds the DNA
only in Eukaryotes
C produces energy
for the cell
B is a pathway for
proteins to travel
Which of the following is FALSE?




(1) holds DNA in
eukaryotic cells
(3) holds food and
waste and is huge
in plant cells
(4) is only present
in animal cell
This is a plant cell
Transport rules- Remember these to be
golden

A) What is the membrane permeable to?



Solute: Diffusion or Active Transport
 Diffusion- moving towards equilibrium
 Active Transport- moving away from equilibrium
Water: Osmosis
B) Osmosis and Tonicity

Calculate percentages of water (if necessary)
 Hypertonic- more water inside; water out; cell shrinks
 Hypotonic- less water inside; water in; cell expands
 Isotonic- same water on both side; no net movement; cell stays the
same size
Transport Trash-ketball!



Each group will compete against each other for
the chance to shoot for team points.
A question will come on the Powerpoint and all
teams will write one answer on a whiteboard.
Teams will put their boards up with the timer
goes off.


The team with the best answer will get to shoot.
The best answer will include


Any work shown neatly
A clear explanation from a person that I choose.


So make sure your whole group knows how to get the
answer
If the person can’t answer I’ll move the next best group
POINT VALUES
1 – Slam Dunk
2 – Creative Slam Dunk
3 – Free Thrown
4 – Creative Free Throw
5 – Touching the
Rollercoaster
There is a 10 second shot
clock once I say your
answer is correct
Trashketball!

A cell of 4% sugar solution is sitting in a
solution 9% sugar solution.
1) Draw this solution
 2) Is this hypertonic, hypotonic, isotonic?
 3) Where does the sugar move?

Trashketball!

A cell with a 41% concentration of sugar
sitting in a 41% sugar solution.
1) Draw this solution
 2) Is this hypertonic, hypotonic, isotonic?
 3) Where does the sugar move?

Trashketball!

A cell of 25% sugar, 75% water solution
is sitting in a solution 15% sugar, 85%
water solution.
1) Draw this solution
 2) Is this hypertonic, hypotonic, isotonic?
 3) If the membrane is permeable to
water only, where will the water move?

Trashketball
1) What will move- solute or solvent?
 2) Which way will it move?

Trashketball
1) What will move- solute or solvent?
 2) Which way will it move?

Trashketball- Tough one!
1) What will move- solute or solvent?
 2) Which way will it move?

This membrane
is NOT
permeable to
solute
Trashketball

If this cell were to undergo active
transport…
What
moves?
Where?

BRAIN DUMP!


On a piece of paper, write down every word that
comes to your mind when you think of passive and
active transport. 2 minutes!
After you complete this activity, write a P if it
relates to passive, write an A if it relates to active,
write B if it relates to both.
