A cell is most likely to shrink when placed in a solution containing a high salt concentration. (OPTION A)
HYPERTONIC SOLUTION -
- The solution containing high salt concentration than the concentration of water.
- The diffusion of water occurs from high concentration to low concentration across the membrane.
- The water osmosis occurs through selective transfer of the substances through the semi-permeable membrane.
- Water flows from the high to the low concentration that is from the cell to the solution thus, distorting the shape of the cell.
- The cell shrinks due to the loss of water molecules and lose water content from the cell.
- The cell becomes turgid when kept in hypertonic solution.

a) When placed in a solution containing a high salt concentration, this makes a cell most likely shrink.
Explanation:
- Solutions with more amount of solute and less water are called Hypertonic solutions.
- When a plant or animal cells is kept in hypertonic solution, there is loss of water and the cell shrinks.
- Water movement is from the cell to the solution because of the decreased amount of solute in the solution.
- Isotonic solutions are those solutions which causes no change in the volume of cell kept in it.
