Explanation:
Detailed explanation-1: -A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis. These three examples of different solute concentrations provide an illustration of the spectrum of water movement based on solute concentration through the process of osmosis.
Detailed explanation-2: -Answer and Explanation: The animal cell(red blood cell) will burst when it is placed in water since it lacks cell wall. On the other hand, when the plant cell is placed in water, the water molecules will move inside the cell causing the cell to swell but since the cell has the cell wall it doesn’t burst.
