Detailed explanation-1: -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. If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell’s volume will remain stable.

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.

Detailed explanation-3: -IMPO tonic means there is a LOWER concentration of solute molecules OUTSIDE the cell than inside.

Detailed explanation-4: -If the solute concentration is higher, that means solvent (water) concentration is low. If the solute concentration is higher outside the cell, then the water (solvent) concentration is higher inside the cell.

Detailed explanation-5: -A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.
