Homework Help: Biology

I am doing a lab on Dialysis to check if starch moves through the differentially permeable membrane of dialysis tubing.We did this by placing a dialysis tube filled with starch solution into a beaker filled with distilled water and a few drops of iodine.

I concluded that starch does not move through the dialysis tubing.

Could you help me with this question:
Describe the solution in the dialysis tube as hypotonic, hypertonic or isotonic with respect to the the distilled water in the beaker.

No one has answered this question yet.
