Question 41
Sara set up an experiment as shown below. Set-up A has water covered with oil in a test tube and no plant. Set-up B has the same arrangement with a rooted plant. After two days, she noticed that there was no change in set-up A while the water level in set-up B decreased. Sara wanted to conduct another experiment to observe whether the absorption of water would be affected by the absence of plant roots. Draw the set-ups that she would need.
