Answer:
(i) Since sugar and salt was present in B and C respectively, water from the trough gathered in the hollowed portions of potato in B and C by the process of osmosis.
(ii) Potato A is necessary for carrying out this experiment because it acts as a control experiment. Control helps us to check what changes occurred during the course of the experiment and helps us to compare the results.
(iii) Water does not gather in the hollowed portion of potato A as it was empty. Water also does not gather in the cup D because the potato used was boiled which makes it inactive as after boiling its protein structure were denatured, resulting in the disruption of the cell membrane.
