A cell when kept in sugar solution, gets dehydrated/reduced in size. Then the solution is
- Hypotonic
- Isotonic
- Hypertonic
- None of these
The Correct Option is C
Solution and Explanation
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.”

Concepts Used:
Transport in Plants
The two types of conducting tissues that are used to transport the water and minerals in plants such as:
Xylem:
Xylem is a long, non-living tube running from the roots to the leaves via the stem. The water is absorbed by the root hair and goes through cell-to-cell movement by osmosis until it reaches the xylem. This water is then transported throughout the xylem vessels to the leaves and is evaporated by the process of transpiration.
The xylem is also composed of lengthened cells like the phloem. However, the xylem is mainly accountable for transporting water to all plant parts from the roots. Since they serve such a vital function, a single tree would have a lot of xylem tissues.
Phloem:
The phloem is accountable for the translocation of nutrients and sugar like carbohydrates, produced by the leaves to areas of the plant that are metabolically in force. It is powered by living cells. The cell walls of these cells structurize small holes at the ends of the cells known as sieve plates.
Means of Transportation in Plants:
Transportation in plants is by 3 means, they are as follows:
- Diffusion
- Facilitated diffusion
- Active Transport
