Question

Differentiate between hypertonic, hypotonic and isotonic solutions. (three points of each) class 9 science ​

Answer 1

Answer:

An isotonic solution has the same solute concentration as the fluid inside a cell. A hypotonic solution has a lower solute concentration than the fluid inside a cell. A hypertonic solution has a higher solute concentration than the fluid inside a cell.

Answer 2

Answer:

The hypertonic, hypotonic, and isotonic solutions can be differentiated based on the solute concentrations.

Explanation:

• A solution that has a lower amount of solute concentration is called a hypotonic solution.
• A solution with a higher solute concentration is termed a hypertonic solution.
• The solution with an equal concentration of solutes on either side of the membranes is known as an isotonic solution.
• When a cell is placed in an isotonic solution, no movement of water or solutes occurs.
• When a cell is placed in a hypertonic solution, water moves out of  the cell.
• When a cell is placed in a hypotonic solution, water moves into the cell.
• The protoplasm shrinks, when a cell is placed in a hypertonic solution.
• Swollen protoplasm is observed when a cell is placed in a hypotonic solution.
• No change in the protoplasm is observed when a cell is placed in an isotonic solution.
