Question

The given figure shows set up of potato osmoscope experiment. Select the option that correctly identified the labels A, B and C.

• A. A-Peeled potato, B-Water, C-Sugar solution
• B. A-Peeled potato, B-Sugar solution, C-Water
• C. A-Unpeeled potato, B-Sugar solution, C-Water
• D. A-Unpeeled potato, B-Water, C-Sugar solution

Answer 1

Answer: (B)

A-Peeled potato, B-Sugar solution, C-Water

in the given figure we can see that endosmosis has taken place because the water level rises from the one which was marked initially with the pin.

A represents a field potato where the potato acts as an osmoscope through which osmosis occurs. the potato SPL because the potato peel does not act as a semipermeable membrane and hence would prevent osmosis from occurring.

For endosmosis to occur the solution kept inside the potato should be of higher concentration hence it is a sugar solution.

Similarly for and osmosis to occur potato should be kept in a solution of low concentration or plain water. Water hence moves inside the potato as it contains a solution of higher concentration.

So the correct option is ' A- peeled potato, B- Sugar solution, C-Water'.
