Just keep going.
Everybody gets better if they keep at it.
Ted Williams
Molecules are in constant motion
- Gases - very quickly
- Liquids - quickly, but not as quickly as gases
- Solids - vibrate in place
Diffusion
- Movement of molecules
- From an area of high concentration to an area of low concentration
- Many molecules of one kind in the same space
- Into available space
- "Spread out"
- Happens naturally
Passive Transport
- Movement of molecules through a selectively permeable membrane .
- Allows some, but not all molecules through
- Selects" molecules allow through
Osmosis
- Special type of diffusion
- Diffusion of water through a selectively permeable membrane
