27. 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
