     c. Is the net direction of water movement into or out of the cell?_______ 

Select the correct word below to indicate the change in the concentration of the sugar solution on each side of the membrane as water molecules move.

a. The solution inside the cell will become__________concentrated with the net movement of water.

Using the diagrams in Model 2 and the answers to the previous questions (14-16), develop definitions for hypertonic extracellular solution.

I recommend that you look this up and provide a short and to the point definition. But, if you look it up, you must tell me that you did so in your answer (hint - I will know anyway, but I want you to be honest).
