  34. 33. Suzie Q wants to know the effect of different colors of light on the growth of plants. She believes that plants can survive best in white light. She buys 5 ferns of the same species, which are all the same age & height. She places one in the white light, one in blue light, one in green light, one in red light and one in the closet. All of the ferns are planted in Miracle-Gro & given 20ml of water once a day for 2 weeks. After 2 weeks, Suzie observes the plants & makes measurements. What is the dependent variable? Growth of plant
