| active transport | involves the use of energy in the form of ATP to move substances across a membrane |
| passive transport | does not require energy & makes use of diffusion and filtration |
| diffusion | moving from regions of high concentration to regions of low concentration |
| osmosis | diffusion of water |
| osmosis- diffusion | water moves from high concentration to low concentration |
| isotonic | when the solution is the same on the outside of the cell and on the inside |
| hypertonic | when the solute is more concentrated outside the cell than inside |
| hypotonic | if the solute concentration outside the cell is lower than the inside of the cell |
| water leaves the cell due to | osmosis |
| in a hypertonic solution the cell | shrinks |
| if a red blood cell is in a hypotonic solution the cell will | swell and burst |
| red blood cell in a hypertonic solution will | shrink |
| filtration | movement of water & solutes thru the membrane by fluid or hydrostatic pressure |
