| Brownian motion | random movement of particles due to kinetic energy |
| diffusion | net movement of particles to an area of higher consentration to an area of lower |
| the rate of diffusion is affected by what? | concentration,temp.and pressure |
| concentration gradient | diiference in concentarion of substances across a space |
| diffusion cannot occur unless a substance is in.......concentrationn | higher |
| osmosis | diffusion of water across a slective permable membrane |
| the three types of solutions are? | hypotonic,isotonic,and hypertonic |
| passive transport | movement across a selective permable membrane by diffusion |
| iso means? | same |
| tonic means? | to stretch |
| hypo means? | under |
| Hyper means? | over |
| the cell must use energy to move particles to counteract the force of diffusion, energy is supplied by...... | ATP |
