Suzie wants to know the effect of different colors of light on the growth of plants. She believes that plants will grow best in white light. She buys 5 ferns of the same species, which are all approximately the same age and height. Then, she places one in white light, one in blue light, one in green light, one in red light and one in natural light. All of the ferns are given 6 hours of light and 20 mL of water daily for 2 weeks.
