A homogenous mixture of more than one substance in which the attachment of the component can be changed is said to be solution.
Types of solution: Solution is of three types comparing with the concentration of cell sap.
- Isotonic solution: When the concentration of cell sap is equal to the concentration of solution outside of the cell it is said to be isotonic solution. This state allows for the free movement of water across the membrane without changing the concentration of solutes on either side.
- Hypotonic solution: When the concentration of the solution outside of the cell is less than the concentration of cell sap it is called hypotonic solution. In the biological fields, this generally refers to a solution that has less solute and more water than another solution.
- Hypertonic solution: When the concentration of solution out side the cell is more than the concentration of cell sap, it is said to be hypertonic solution. A hypertonic solution is one where the concentration of solutes is greater outside the cell than inside it.
