front 1 Diffusion | back 1 the process of moving molecules from areas of high concentration to low concentration until equilibrium is reached. |
front 2 Osmosis | back 2 diffusion of water from areas of high concentration of water molecules to low concentration of water molecules. (Remember that the amount of solute present can affect this. ) |
front 3 facilitated diffusion | back 3 Diffusion of molecules that uses a channel protein to move the molecules into or out of the cell. |
front 4 active transport | back 4 movement of molecules from areas of low concentration to high concentration (against the concentration gradient) Requires ATP Requires a special transport protein |
front 5 Endocytosis | back 5 a type of active transport that brings large molecules into the cell. The cell membrane envelops the particle and is pushed into the cell. |
front 6 Phagocytosis | back 6 cell eating (taking in large solid particles by endocytosis) |
front 7 Pinocytosis | back 7 cell drinking (taking in large droplets of liquid into the cell by endocytosis) |
front 8 exocytosis | back 8 removing large particles from the cell. The particle is enclosed in a vesicle and the phospholipids of the vesicle fuse to the cell membrane and push the contents out of the cell. |
front 9 passive transport | back 9 transport of molecules that moves with the concentration gradient does not require energy includes diffusion, osmosis, facilitated diffusion |
front 10 ATP | back 10 adenosine tri-phosphate Energy used for chemical reactions |
front 11 hypertonic environment | back 11 solution that is highly concentration cells placed in this solution will shrivel |
front 12 hypotonic environment | back 12 solution that has little to no solute concentration cells placed in this solution will swell and burst |
front 13 isotonic | back 13 environment where there water leaving and entering the cell is at equillibrium |
