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: -In hypotonic solutions, there is a net movement of water from the solution into the body. A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis.

Detailed explanation-3: -A hypertonic solution has increased solute, and a net movement of water outside causing the cell to shrink. A hypotonic solution has decreased solute concentration, and a net movement of water inside the cell, causing swelling or breakage.

Detailed explanation-4: -A hypotonic solution causes a cell to swell, whereas a hypertonic solution causes a cell to shrink.

Detailed explanation-5: -(ii) Hypotonic solution: A solution having a lesser concentration of solute inside as compared to outside the cell is called a hypotonic solution. In a hypotonic solution, a cell progressively gains water through endosmosis.
