| A | B |
|---|
| diffusion | the movement of molecules from high concentration to low concentration |
| equilibrium | molecules will move in and out an equal rate |
| cell membrane | job is to control what goes in and out of the cell |
| selectively permeable | means it only allows certain materials to pass through (pores or openings) |
| osmosis | the diffusion of water |
| hypotonic | solution with more water outside the cell/water moves in-cell will swell (bigger) |
| isotonic | water out is the same as water in the cell /cell stays same size |
| hypertonic | water will move out to the cell /cell will shrivel -smaller |
| active transport | movement of molecules from low concentration to high using energy |
