| Transport | all processes by which substances pass into and out of cells and move within the organism |
| Absorption | passage of materials across a cell membrane |
| Circulation | the movement of materials within a cell or between parts of an organism |
| Semipermeable | allows the passage of some materials but not others |
| Diffusion | the movement of materials from an area of high to an area of low concentration |
| Concentration Gradient | the difference between a region of greater and a region of lesser concentration |
| Osmosis | diffusion of water |
| Osmotic pressure | pressure resulting from osmosis |
| Turgor | effect of osmotic pressure in plant tissues |
| Plasmolysis | the shrinking of the cytoplasmof a cell due to loss of water by osmosis |
| Passive transport | transport without the expenditure of cellular energy |
| Active transport | transport with the expenditure of cellular energy |
| Cyclosis | a streaming movement of the cytoplasm(unicellular transport) |
| Circulatory System | all the organs that function together to perform circulation in an organism |
