Suzie Q wants to know how different colors of light effect 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 all approximately the same age and height. She places one in 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-Grow and given 20 mL of water once a day for 2 weeks. After the two weeks, Suzie observes the plants and measurements. What is the control?
fern in the closet

Justin B. believes that the temperature lowering during the fall months is what causes the color of the leaves to change. He set up an experiment wherein he placed some plants in 80 degree rooms and some in 60 degree rooms. He then observed the color of the leaves for a total of 1 month. At the end of the month Justin observed that ¾ of the plants in the 60 degree temperature had been to change colors and only ¼ of the plants in the 80 degree temperature began to change colors. Identify the control group.
60 degree room
