Detailed explanation-1: -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-2: -A hypotonic solution would have a lower osmolarity than the fluids inside the cell. This means that water would move into the cell from the surrounding solution. Essentially, the water moves to dilute the solution so that it has the same concentration on both sides of the membrane.
Detailed explanation-3: -Water moves by osmosis, which is a type of diffusion, into and out of the cell. Through the cell membrane, water molecules flow through osmosis from a lower solute concentration to a higher solute concentration. Water can therefore travel because of a concentration gradient without using any energy.
