Lawrence, a student in biology class, was conducting an experiment to see if different types of plant foods would affect the growth of bean plants. One day when Lawrence was feeding the plants, he accidentally spilled salt in the soil around the roots of one of the bean plants. The next day he noticed that the plant had slowed dramatically. Lawrence decides to prepare two slides: one from a plant not exposed to the salt and one from the plant exposed to the salt. The following is what he observed. Using excellent biology vocabulary, describe what happened to make the plant wilt in this situation.
