One celery stick is placed in a beaker of pure (100%) water. A different celery stick is placed in a beaker of an 80% water and 20% solute solution. Predict the outcome.

Answer: In the case of the celery in salt water, water would leave the cells and the stalk will become wilted.

In the case of the beaker with plain water, the water will move into the cells in the stalk. You would see this better if the stalk was already wilted.
