What do you notice?
3
Concentration Gradients
The motion of each molecule is random and independent of the other molecules in solution.
Barring outside influence, molecules have a net movement from an area of high concentration to an area of low concentration.
4
Multiple Choice
Which side has a higher concentration of molecules?
5
Multiple Choice
The net movement of molecules would be from...
6
Open Ended
Explain what happened to the dye in the water over time.
7
Simple Diffusion
Movement of small or uncharged molecules down the concentration gradient directly through the cell membrane.
example: O2 or CO2
8
Facilitated Diffusion
Movement of larger or charged molecules down the concentration gradient through a transport protein.
The transport protein is specific to the molecule crossing the membrane.
examples: glucose, Na+, Cl-, K+

Multiple Select
10
Osmosis
type of facilitated diffusion
movement of water across the membrane through a special transport protein (an aquaporin)
net movement of water is down water's concentration gradient
