Carrot slices placed in 0.2M salt solution for several hours becomes flaccid (limp). Carrot slices placed in freshwater for several hours becomes turgid (stiff). From this, we can deduce that the

1. freshwater is hypertonic and the salt solution is hypotonic to the cells of the carrot slices.

2. freshwater and salt solution are both hypotonic to the cells of the carrot slices.

3. freshwater is isotonic and the salt solution is hypertonic to the cells of the carrot slices.

4. freshwater is hypotonic and the salt solution is hypertonic to the cells of the carrot slices.

5. freshwater and the salt solution are both hypertonic to the cells of the carrot slices.

If the carrot slices become flaccid after several hours in 0.2M salt solution and become turgid in freshwater, it means that the salt solution is hypertonic while the freshwater is hypotonic to the cells of the carrot slices. Option 4 would be the right option.

Hypertonic solutions are solutions with low water potential when compared to that of the cells placed in them. Thus, they usually draw water from cells and make them go flaccid.

Hypotonic solutions are solutions with high water potentials when compared to the water potentials of the cells placed in them. Thus, they usually lose water to cells and make them become turgid.

Isotonic solutions have the same water potential as the cells placed in them. Thus, cells neither gain nor lose water in them because there is no net movement of water.

Therefore, since the carrot cells became flaccid in the salt solution but turgid in freshwater, the salt solution and the freshwater are said to be hypertonic and hypotonic respectively.

Option 4.

The fresh water is hypotonic and the salt solution is Hypertonic.

Explanation:

Hypotonic solution is a solution that have little dissolved solutes i.e low osmotic pressure compare to other solution. When a cell is put in hypotonic solution, it take in water and the cell swell up and it does not burst due to it's cell wall thereby becoming turgid or hard.

Hypertonic solution is the solution where the concentration of solute is higher outside the cell than inside the cell. Example is saline water.when a cell is placed in Hypertonic solution it will shrinks because it losses water.
