Debbie is doing a school project to see if plants must have both water AND sunlight to grow. She decides to put some plants in a window and others in a dark closet.

She concludes that the plants in the window that received water grew the tallest and had the healthiest appearance. Is her conclusion valid based on the information she gathered? What evidence supports her claim?
