Diffusion and Osmosis
Diffusion and osmosis are types of passive transport
- Passive transport is the movement of molecules across a cell membrane without energy input
from the cell.
Diffusion
- Diffusion is the movement of molecules in a fluid or a gas from a region od higher
concentration to a region of lower concentration.
- A concentration gradient is the difference in the concentration of a substance from one
location to another.
Osmosis
- Water molecules of course, also diffuse. They move across a semipermeable membrane from
