Which way would the blue molecules in the diagram at the right move if they are able to diffuse freely across the membrane? Into or out of the cell?
If a cell is placed in a solution where there is a high concentration of salt (solutes), will water move INTO the cell, or OUT OF the cell?
What type of solution is the solution in #2? (Hypertonic, Hypotonic, or Isotonic?)
If a cell is placed in a solution where there is a low concentration of solutes (for example, distilled water with nothing dissolved in it), will water move INTO the cell, or OUT OF the cell?
What type of solution is the solution in #4? (Hypertonic, Hypotonic, or Isotonic?)
Diffusion and osmosis are both types of passive transport. Does passive transport involve energy use by the cell to complete?
Why is osmosis considered to be facilitated diffusion?
Imagine that your Gummy Bear represents a cell. Would the inside of the gummy bear represent intracellular fluid, or extracellular fluid? Explain
Would the distilled water surrounding your gummy bear represent intracellular fluid, or extracellular fluid? Explain.
Look back at your responses for Questions #4 and #5, explain what happened to your gummy bear when placed in distilled water. (Some terms that may apply that you can use in your explanation: intracellular, extracellular, hypertonic, hypotonic, isotonic, osmosis, diffusion, concentration, solute)
