Detailed explanation-1: -Final answer: If a solution outside the cell is more concentrated so that the cell loses water to its environment and shrinks the external solution is said to be hypertonic to the cell contents.

Detailed explanation-2: -A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell. Water crosses the cell membrane in both directions, but more water leaves the cell than enters it. Therefore, the cell will shrink due to exosmosis.

Detailed explanation-3: -If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume. If the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane, then that solution is hypotonic to the cell.

Detailed explanation-4: -Hypotonic solution is a solution which has a greater concentration outside the cell and hypertonic solution is a solution which has a greater concentration inside the cell.

Detailed explanation-5: -Hypertonic solutions have a higher solute concentration than inside the cell. This causes water to rush out making the cell wrinkle or shrivel.
