A cup of water with a drop of blue food dye will reach equilibrium within 10 minutes. This
means that all molecules are equally spread apart and will continue to move because molecules
are always in ______________.
A gummy bear absorbs water through the outer membrane. The movement of water across a
semipermeable membrane is called _____________________.
A fresh stalk of celery placed into a ____________________solution will shrink. This is because
water in the celery will be pulled toward the higher percentage of salt solution.

10. Describe how a cell reaches equilibrium with its surroundings if there are 15 water molecules
inside the cell and 33 water molecules outside the cell. You may draw a diagram if you wish.
What number of water molecules will be inside and outside of the cell at equilibrium?
Remember, water always travels from higher concentrations to lower concentrations. High to
Low… Go with the Flow! Remember… you are dealing with water, not salt!
