| active transport | movement of materials through a membrance across a concentration gradient REQUIRING ENERGY |
| endocytosis | a process by which a cell surrounds and takes in material from the environment by engulfing it with the plasma membrane and releasing it as a vacuole in the cell |
| exocytosis | the expulsion or secretion of materials from a cell |
| facilitated diffusion | passive transport of across a membrane using transport proteins |
| hypertonic solution | a solution where the concentration is HIGHER outside the cell than iside the cell |
| hypotonic solution | a solution where the concentration is LOWER outside the cell than inside the cell |
| isotonic solution | a solution where the concentration is the SAME outside the cell as inside the cell |
| osmosis | movement of water across a selectively permeable membrane |
| passive transport | movement across a membrane that REQUIRES NO ENERGY - for example DIFFUSION |
