- Diffusion
- substances have to pass through the cell membrane to get into or out of a cell.
- Diffusion occurs when particles spread
- They move from a region where they are in high concentration to a region where they are in low concentration.
- Diffusion happens when the particles are free to move.
- diffusion does not occur in solids
- Particles diffuse down a concentration gradient, from an area of high concentration to an area of low concentration
- This is how the smell of cooking travels around the house from the kitchen, for example
