I will discover the meaning of ISOtonic, HypOtonic, Hypertonic
#1 PICK UP Lab Sheet!
Write your NAME & PD at TOP, RIGHT
Think about 2 group members to work with you
#2 LOOK OVER READING from
ISN pages 107 AND 109
Active/Passive Transport
Concentration Gradient
Sodium Potassium Pump
Protein Channels
Diffusion/Osmosis/ Facilitated Diffusion
Dynamic Equilibrium
Energy
Inhibitors
Selective Permeability
Osmosis/Diffusion

2. Selectively Permeability of the
Cell Membrane
Selective Permeability

3. Transport Through a Cell LAB
AS A CLASS
Demo #1 Raman Noodles
DRY vs WET over night
What happened to Raman when in water…?
How did the mass change?
Demo #2 Potatoes
1cm vs 2cm vs 3cm  Covered in blue stain
Look at Data Table, Observations
Answer questions…

4. Transport LAB, cont. GROUPS OF 3 Activity #3 Grapes
READ Background FIRST… NOW
Under PROCEDURE, cross out #1
If not done already  NUMBER/LABEL your cups
Look at the DATA TABLE to do this!
Identify your cups as YOURS…!
To MASS the grapes – use the ‘boat’…. LISTEN!
When finished, place all 5 cups on counter under your classes Post-It notes…
Activity #4 Gummy Bears
Same process as with grapes  See ABOVE!!!

5. Notes…
ISN p.108
Q: Why are cells so small? What factors limit cell size to microscopic?
A: The ratio of cell membrane Surface Area to Cell Volume is a factor that limits cell size… AS CELLS INCREASE IN SIZE THE SA/V RATIO DECREASES. If a cell grows too big then its volume will not have enough surface area to support its needs by diffusion.
