Every solution has two components, solute (sugar, salt etc.) and solvent
(water). The solute dissolves in the solvent and forms a solution. Here
the animal cell is kept in dilute external medium that means hypotonic
Hypotonic solution: In this solution the solute
concentration is lower than that of the cell fluid concentration. As a
result, water moves into the cell from the surrounding medium through a
cell membrane. This results in causing the cell to swell and burst.
