The following diagram is set up to demonstrate an experiment.
Five plants A, B, C, D, and E were placed in a beaker containing water. The water in each beaker was covered with a layer of oil. The leaves were removed from plant D in plant B, upper surfaces of all the leaves were covered with Vaseline, in-plant C the lower surfaces of all the leaves were covered with Vaseline and plant E was exposed to strong light. The beakers were then left for a few hours and at the end of the experimental period, weights of each beaker were taken.
Write the correct answer out of the five available choices given under each question:
I. In which beaker would you expect the greatest decrease in weight?
(i) A (ii) B (iii) C (iv) D (v) E
II. In which beaker the change of weight would be minimum?
(i) A (ii) B (iii) C (iv) D (v) E
III. Which plant would remain healthy for a longer period of time?
