In a few days you will notice that the water in the vessel containing the clover is disappearing much more rap- idly than that in the other vessel. As soon as the clover begins to wilt take it out of the water and by Relative amounts of water at the beginning of the experiment. Relative amounts of water at the end of the experiment. measuring compare what remains in the two vessels. Of course, both have lost by evaporation—that is, both have ''dried up,' as we say—but, if the vessels are of the same size, there should be ecpial evaporation. Why, then, should not the remainders be equal? Be- cause the clover plant has been using up water. The difference between what remains in the two cans repre- sents the amount used by the clover plant. H01V Plants Use [Fa/^r.^Plants make use of water in two ways. In the first place, they use it as food just the same as animals do. In the second place, a plant cannot eat solid food. It has neither mouth nor teeth and it must suck in its food in liquid form
