    Solution Preview

    When Elodea leaves are placed in distilled water, what happens? Since the cells are hypertonic to the water (the water being hypotonic), water flows from the distilled water through the cell wall and plasma membrane and into the interior of the cells. This takes place because there are more solutes inside the cell than outside. Another way to look at this is that there is a higher concentration of water outside the cells and ...

    Solution Summary
