| passive transport | movement of particles through the cell membrane from high to low concentration; no energy required |
| active transport | movement of particles through a cell membrane from low to high concentration; energy is required |
| facilitated diffusion | channel or carrier protein in the cell membrane provides transport through a cell membrane |
| osmosis | diffusion of water through a selectively permeable membrane from hogh to low concentration |
| endocytosis | cell membrane surrounds material and forms a vesicle as it draws material into the cell |
| exocytosis | vesicle inside cell fuses with cell membrane and releases material out of the cell |
| phagocytosis | cell membrane surrounds and captures large particle using its cell membrane as it brings material into the cell |
| pinocytosis | cell membrane engulfs liquid and small dissolved particles and forms vesicle as it brings material into the cell |
