| A | B |
| passive transport | does not require energy from cell |
| diffusion | movement of molecules from greater to lesser concentration |
| hypertonic | molecules exit the cell |
| isotonic | equal concentrations |
| endocytosis | passage of large molecules into the cell |
| molecule | can not pass through the menbrane |
| solute | molecule |
| active transport | energy needed from the cell |
| osmosis | the diffusion of water from an area of greater concentration to an area of lesser concentration |
| hypotonic | molecules enter the cell |
| equilibrum | when the number of molecules is the same throughout the cell |
| exocytosis | passage of large molecules to the outside of the cell |
| solvent | OH2O |
| semi-permeable | only lets certain things in |
