Dejon wants to test whether plants need soil to grow. He cuts two branches off of the plants and weighs them. He puts each in a glass of water and places one in an area with sunlight and the other in a shaded corner of the room. He makes sure that the glasses always have water. Over the next three months, the plants grow roots and get bigger. Do plants need soil to grow? Justify your answer using data from both Katia’s and Dejon’s experiments.
