| Term | Definition |
|---|
| diffusion | the movement of particles from an area where their concentration is high to an area where their concentration is low |
| passive transport | the movement of materials into or out of the cell withou the xpenditure of energy |
| equilibrium | particles will continue to diffuse into or out of a cell until their concentration is the same on both sides of the cell membrane |
| semi-permeable membrane | means that some particles cam pass across the membrane while others can not |
| concentration gradient | the diffierence in concentration that makes osmosis possible |
| hypertonic solution | a solution whre th concentration fo solute outside the the cell is higher than the concentration inside the cell |
| solute | the substance that is dissolved |
| solvent | the substance that does the dissolving |
| solution | a mixture that contains both a solute and a solvent |
| hypotonic solution | a solution whre the concentration of the solute inside the cell is greater than the concentration solute outside the cell |
| facilitated diffusion | a process that allows a few molecules to pass throught the cell membrane more easily than might be expected |
| active transport | movement of materials against the concentration gradient that requires energy |
| endocytosis | transport of large molecules by movement of the cell membrane |
| exocytosis | the opposite movement of endocytosis |
| homostasis | the ability of a cell to regulate its internal conditions despite changes in the environment |
| metabolism | the sum total of the body's chemical activities |
