  Side A   Side B
1
Diffusion
 
Molecules (solutes) move through solutions from areas of high concentration to areas of low...
2
Density's effect on Diffusion?
 
Dense slows diffusion (agar vs. water)
More molecules to get through
3
Pheynolphthalein
 
Reacts with Base PH turning PINK
Cannot pass through membrane because it is POLAR
4
Iodine
 
Reacts with Starch
Passes through membrane because it is Non-Polar
5
NaOH
 
Turns Phenyolphthalein pink
Passes through membrane because it is Non-Polar
6
Starch
 
Reacts with Iodine
Doesn't pass through membrane because it is Polar
7
Water Potential
 
Combined effects of concentration and pressure that affect the flow of water.  Water will...
8
Hypertonic Solution
 
High molecule concentration of solutes.  Water flows TO this.
9
Hypotonic Solution
 
Low molecular concentration of solutes.  Water flows AWAY from this.
10
Plasmolysis
 
Shrinking cytoplasm of a plant cell due to diffusion of water out of a cell and into a hypertonic...
11
Isotonic Solution
 
Evenly distributed molecule concentration of solutes.  Water has even flow in/out.
