Experiment 1 – Movement of water but no movement of glucose
There is distilled water in both the tubing and in the test tube. Even though there is no concentration gradient, water molecules will still move across the membrane. Since there is no glucose, there will be no movement of glucose.

In experiments 2, 3 and 4, there is glucose and water molecules present. Hence, water and glucose molecules will move across the the membrane.
