Suzie Q. wants to know how different colors of light affect the growth of plants. She believes that plants can survive the best in white light. She buys 5 ferns of the same species, which are approximately the same age and height. She places one in white light, one in blue light, one in red light, and one in the closet. All of the ferns are planted in Miracle-Grow and given 20 ml of water once a day for 2 weeks. After two weeks, Suzie observes the plants and makes measurements.
