Question

A cell when kept in sugar solution, gets dehydrated/reduced in size. Then the solution is

• A. Hypotonic
• B. Isotonic
• C. Hypertonic
• D. None of these

Answer 1

Answer: (C)

Hypertonic

Answer 2

The correct option is (C): Hypertonic

If the cell placed in a sugar solution gets dehydrated, that means the solution is hypertonic, which means the concentration of solute (in this case, sugar) is higher compared to that of the cell. Hence, osmosis will occur from the semi-permeable plasma membrane of the cell. The water inside the cell will diffuse to the outer surroundings, which will make the cell shrink in size

TERMS USED IN OTHER OPTIONS:

• Hypotonic: a solution with a lower solute concentration compared to the inside of the cell. Water will move into the cell, causing it to swell.
• Isotonic: A solution with the same solute concentration as the inside of the cell. There's no net movement of water.
• Hypertonic: A solution with a higher solute concentration compared to the inside of the cell. Water will move out of the cell, causing it to shrink.

To conclude, the term that can be used to accurately describe the given condition is “hypertonic.”
