Question	Answer
passive transport	when substances cross the membrane without the use of energy
diffusion	movement of molecules from an area of higher concentration to an area of lower concentration
concentration gradient	the difference in amounts of substances on either side of a membrane-usually one side has more than the other
equilibrium	When the concentration of substances are equal on both sides of a membrane
plasmolysis	lack of water in a plant. It wilts
cytolysis	the bursting of red blood cells when placed in a hyotonic solution
facilitated diffusion	aided by special proteins imbedded in the membrane molecules cross without energy
carrier protein	in the membrane, this helps molecules travel across the membrane without using energy
ion channel	small passageways in the membrane that allow Na+ or Cl- to pass through
osmosis	when water moves from one side of a membrane to another-moving from higher to lower concentration
hypotonic	when the solution outside a cell is less concentrated than inside the cell
hypertonic	when the solution outside a cell is more concentrated than inside the cell
isotonic	when a solution outside a cell is the same concentration as inside the cell
contractile vacuole	organelle that removes water for some organisms like paramecium
turgor pressure	the pressure that water exerts on the cell walls and central vacuoles of plants.
