Detailed explanation-1: -If we take seawater as an example of a solution, the salt is called the solute (the particles that are dissolved) and the water is the solvent (the liquid that dissolves the particles).

Detailed explanation-2: -Saltwater is the solution, the salt is the solute, and the water is the solvent. A hypotonic solution is one that has less of a dissolved substance, or solute, in it. A hypertonic solution has a greater concentration of solute when compared to another solution.

Detailed explanation-3: -Water moves into and out of cells by osmosis. If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic.

Detailed explanation-4: -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-5: -An egg with a dissolved shell is placed in pure water for 48 hours. Water will move in and out of the cell equally, and the cell with neither shrink nor swell. The egg will gain water and swell.
