| 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 |
| plasmolysis | cell deflates due to loss of turgor pressure |
| cytolysis | cell bursts due to increase in turgor pressure |
| turgor pressure | keeps cell inflated |
| facilitated diffusion | moves material from high to low concentration using carrier or transport proteins |
| active transport | mplecules move from low to high concentration using carrier proteins and ATP's energy |
| endocytosis | process by which a cell takes material into the cell by infolding of the cell membrane |
| phagocytosis | white blood cells engulf and attack bacteria |
| cell membrane | thin, flexible barrier around a cell; regulates what enters and leaves the cell |
| lipid bilayer | double-layered sheet that forms the core of nearly all cell membranes |
| isotonic | when the concentration of two solutions is the same |
| hypertonic | when comparing two solutions, the solution with the greater concentration of solutes |
| hypotonic | when comparing two solutions, the solution with the lesser concentration of solutes |
| exocytosis | process by which a cell releases large amounts of material |
| concentration | the mass of solute in a given volume of solution, or mass/volume |
