Detailed explanation-1: -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-2: -If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic. Cells placed in a hypotonic solution will take in water across their membranes until both the external solution and the cytosol are isotonic.

Detailed explanation-3: -Cells placed in a hypotonic solution will take in water across their membrane until both the external solution and the cytosol are isotonic. A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst) when placed in a hypotonic solution.

Detailed explanation-4: -If a cell is placed in a hypotonic solution, the cell will swell and burst.

Detailed explanation-5: -Explanation: the hypotonic solution has a higher water potential than that of the cell, so water will enter the cell from a region of higher water potential to a lower water potential down a water potential gradient across a partially permeable membrane via osmosis.
