| diffusion | movement of particles from high concentration to low concentration |
| osmosis | diffusion of water through the cell membrane |
| passive transport | diffusion of particles through proteins in the cell membrane from high to low concentration |
| active transport | the movement of particles through proteins in the cell membrane against the direction of diffusion; requires cells to use energy |
| endocytosis | process in which a cell membrane surrounds a particle and encloses it in a vesicle to bring in the cell |
| exocytosis | the process used to remove large particles from a cell |
| ATP | the molecule that provides energy for a cell's activities |
| cell membrane | a phosopholipid layer that covers a cell's surface and act's as a barrier between the inside of a cell and the cell's environment |
