Carry out the following osmosis experiment:Take four peeled potato halves and scoop each one out to make potato cups. One of these potato cups should be made from a boiled potato. Put each potato cup in a trough containing water. Now,(a) Keep cup A empty.(b) Put one teaspoon sugar in cup B.(c) Put one teaspoon salt in cup C.(d) Put one teaspoon sugar in the boiled potato cup D.Keep these for two hours. Then observe the four potato cups and answer the following:(i) Explain why water gathers in the hollowed portion of B and C.(ii) Why is potato A necessary for this experiment?(iii) Explain why water does not gather in the hollowed – out portions of A and D.


(i) Water from the trough gathered in the hollowed regions of potato in B and C due to the presence of sugar and salt in B and C, respectively.
(ii) Potato A is required for the completion of this experiment because it serves as a control. Control allows us to see what changes occurred over the course of the experiment and compare the outcomes.
(iii) Because potato A’s hollowed half was empty, water did not collect. Water does not collect in cup D because the potato was boiled, rendering it inactive because its protein structure was denatured during boiling, leading in cell membrane breakdown.

Final Answer : Hence, the results can be studied this way.
