ANATOMY

Detailed explanation-1: -Water molecules move along the concentration gradient, that is, from higher concentration to lower concentration. So, for a cell to swell, it has to be placed in a hypotonic solution .

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: -Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. Water can enter the cell by diffusion through the cell membrane or through selective membrane channels called aquaporins, which greatly facilitate the flow of water.

Detailed explanation-4: -It is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration. Diffusion will continue until the concentration gradient has been eliminated.

Detailed explanation-5: -A hypotonic solution has decreased solute concentration, and a net movement of water inside the cell, causing swelling or breakage.
