Researchers are studying the way plants move in response to stimuli. Which scenario could be used to test phototropism? A) Two s
ets of plants could be placed in a dark room and the growth monitored. B) Two sets of plants could be placed in a lighted room and the growth monitored. C) One set of plants could be placed in a lighted room and one set in a dark room; plant growth is monitored. D) One set of plants could be placed in a room with a light on the right side and one set in a room with a light on the left side; plant growth is monitored
In order to conduct a research you should have an dependent variable, independent variable and the control variable. so in order to study phototropism, then you should need sun light and the growth of the plant and you must have a control that why you need a dark room.
