Given alongside is the diagram of an experimental set-up to demonstrate a certain phenomenon in plants.

Name the phenomenon being demonstrated.

The figure below represents the set-up at the start of certain experiment to demonstrate an activity of plants:
(i) What is the aim of the experiment?
(ii) Why has oil been put in each test tube?
(iii) What will be the observations in the two test-tubes after about 2-3 days?
(iv) Give reasons to explain any change observed as answered in (iii) above.
(v) Why has the test-tube b without the plant, been taken in the experiment?

Plants lose water by the process of transpiration.
