TYPES OF SOLUTION ON THE BASES OF CONCENTRATION

Hypotonic Solution- It is a dilute solution is the solution has higher water concentration than inside the cell as a result of which cell gain water and swells up, may be burst. Such solution is known as Hypotonic Solutions

• Cell gain water and swells up process is known as Endo-Osmosis.

Hypertonic Solution- It is a concentrated solution i.e. the solution has lower concentration of water than inside the cell, as a result of which cell loose water and shrink by Osmosis. Such as solution is known as Hypertonic solution.

• Cell loose water and shrink i.e. Exo-osmosis

Isotonic Solution- The Solution has some water concentration as inside the cell, then there no overall movement of water and the cell size remains same.

Amount of water enter inside the cell is equal to the water move outside the cell
