Detailed explanation-1: -A hypotonic tonic solution is any external solution that has a low solute concentration and high water concentration compared to body fluids. In hypotonic solutions, there is a net movement of water from the solution into the body.

Detailed explanation-2: -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-3: -In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower solute concentration is hypotonic.

Detailed explanation-4: -A hypotonic solution has a lower concentration of dissolved particles than a cell. A cell in a hypotonic solution will swell.

Detailed explanation-5: -Hypotonic solution refers to a solution containing a lower amount of solute in comparison to the solute concentration in other solutions, across a semipermeable membrane. Such a solution has a decreased solute concentration and a total movement of water in the cell.
