| A | B |
| diffusion | movement of molecules from high to low concentration until equilibrium is reached |
| equilibrium | dynamic state where the concentrations on eother side of a cell membrane are equal, What moves in = what moves out |
| osmosis | diffusion of water |
| hypertonic | solution that will cause water to move out of the cell |
| isotonic | solution that will cause no chance in the cell's volume or shape |
| turgor pressure | keeps the plant cell inflated |
| facilitated diffusion | moves material from high to low concentration using carrier or transport proteins |
| active transport | molecules move from low to high concentration using carrier proteins and ATP's energy |
| endocytosis/exocytosis | Used for molecules too large to enter or exit cell xit cell cell |
| phagocytosis | white blood cells engulf and attack bacteria |
| pinocytosis | cells engulf large volumes of dissolved solutes |
| phospholipid | the primary lipid that makes up the cell membrane |
| semi-permeable | the term that refers to the cell membrane's ability to allow some molecules through while restricting others. |
| protein pump | This is a proteins that uses ATP energy to move molecules from low to high concentration across the cell membrane |
| Na-K pump | This pump uses ATP energy to move Na (sodium) out of the cell and K (potassium) in to the cell |
| concentration gradient | Unequal distribution of solute in a given area |
| homeostasis | ability for a system to regulate its internal environment |
| hypotonic | solution that will cause the cell to expand and possibly burst |
| solute | dissolved particles in a solution |
| solvent | the part of the solution that does the dissolving |
