| diffusion | movement of molecules from high to low concentration until equilibrium is reached |
| equilibrium | dynamic state where the concentrations on eother side of a cell membrane are equal, What moves in = what moves out |
| osmosis | diffusion of water |
| facilitated diffusion | moves material from high to low concentration using carrier or transport proteins |
| active transport | molecules move from low to high concentration using carrier proteins and energy from ATP |
| endocytosis | Process of taking in materials thru infoldings or pockets of the cell membrane |
| exocytosis | contents of cell exit the cell via fusion of the membrane of the cell fusing with the membrane exiting material |
| isotonic | concentration of solutes is the same inside and outside the cell; water moves equally in both directions |
| hypertonic | the solution has a higher solute concentration than the cell. Water moving out of the cell causes the cell to shrink |
| hypotonic | the solution has a lower solute concentration than the cell. Water moves into the cell causing the cell to swell. |
