Question

Name the process/term for the statements given below:

1. A solution whose concentration is equal to that of the cell sap.
2. A solution whose concentration is greater than that of cell sap.
3. A solution whose concentration is lower than that of cell sap.
4. Two solutions having equal osmotic pressure.

Answer 1

Cell sap:

The fluid produced by the cytoplasm of a living plant cell is known as the cell sap.

a. A solution whose concentration is equal to that of the cell sap

1. An isotonic solution is a solution whose concentration is equal to the cell sap.
2. An isotonic solution has the same water concentration as inside the cell, so there will be no osmotic pressure.

b. A solution whose concentration is greater than that of cell sap

1. A hypertonic solution is a solution whose concentration is greater than that of the cell sap.
2. A hypertonic solution has low water concentration and high solute concentration as compared to the cell sap, so there will be high osmotic pressure.

c. A solution whose concentration is lower than that of cell sap

1. A hypotonic solution is a solution whose concentration is much lower than that of the cell sap.
2. A hypotonic solution has lower solute concentration and high water concentration as compared to the cell sap, so there will be a lower osmotic pressure.

d. Two solutions having equal osmotic pressure

1. Isotonic or iso-osmotic solutions are the two solutions that have the same osmotic pressure.
2. There will be no movement of solvent between the two solutions.
