Beena conducted an experiment in which two potato tubers were peeled and a cavity was made in each of them. One of the potato tuber was boiled while the other one was not. The cavities in both tubers were filled with distilled water and they were then placed in petri-dishes containing 1M sucrose solution. The results are shown in the given figures.
When a potato is boiled osmosis takes place. Water moves from the area of less salt to more salt, that is water will move inside the potato because of higher salt concentration.
So, when boiled and unboiled potato are kept filled with water that is distilled then the water in boiled potato tuber reduces due is evaporation the water turns into vapours whereas in unboiled potato tuber the salt concentration inside is more.
Therefore, water moves inside by osmosis.
In unboiled potato, no sucrose was found as it already has a high concentration of
solvent, so no exosmosis takes place, similarly in boiled potato water content
is more so sucrose moves inside and exosmosis takes place.
Hence, option D is correct.
