A cell is a basic unit of structure and function in all living organisms. All cells have a plasma membrane that surrounds the cytoplasm, which contains the cell's organelles and other contents. In order for a cell to function properly, the concentrations of various ions and molecules must be maintained within certain ranges. This process is called osmoregulation, and it relies on the selective permeability of the plasma membrane.

If a cell is placed in an external solution with a different concentration of solutes than its cytoplasm, water will either enter or leave the cell in order to equalize the solute concentration on both sides of the membrane. This process is called osmosis, and it results in the swelling or shrinking of the cell. The tonicity of a solution describes how it affects a cell in this way.

What is tonicity?

What is tonicity?

The term tonicity describes the osmotic pressure of a solution. The osmotic pressure is the suction power with which a solvent (in our case water) is absorbed by a semipermeable membrane from a less concentrated (hypotonic) to a more concentrated (hypertonic) solution.

Isotonicity

Isotonicity

The cell described in Example 1 is placed in a test tube of water containing 0.02 molar glucose. Since glucose is not actively transported into the cell, the external solution is isotonic relative to the cytoplasm of the cell.

Hypertonicity

Hypertonicity

The cell described in Example 1 is placed in a test tube of water containing 0.02 molar glucose. Since the cytoplasm has a concentration of 0.02 molar glucose, the external solution is isotonic relative to the cytoplasm of the cell.

Hypotonic solutions

Hypotonic solutions

If a cell is placed in a hypotonic solution, water will flow into the cell and the cell will swell. This is because the concentration of solutes is higher inside the cell than outside, so water flows from areas of high concentration (outside the cell) to areas of low concentration (inside the cell).

Cellular swelling

Cellular swelling

If a cell is placed in a solution with a lower concentration of osmotically active particles than inside the cell, water flows into the cell. This leads to an increase in volume, which is also called cellular swelling.

Osmosis

Osmosis

If a cell is placed in a solution with a lower concentration of osmotically active particles than inside the cell, water will flow into the cell by osmosis. This will lead to an increase in volume and pressure inside the cell. If the cell has a cell wall, as is the case with plant cells, this process is called plasmolysis. Animal cells do not have a cell wall and will therefore burst when exposed to high osmotic pressure.

Plasmolysis

Plasmolysis

The external solution is hypotonic relative to the cytoplasm of the cell.

Turgor pressure

Turgor pressure

The cell described in Example 1 is placed in a test tube of water containing 0.02 molar glucose. Since glucose is not actively transported into the cell, the tonicity of the external solution is isotonic relative to the cytoplasm of the cell.

Conclusion

Conclusion

The external solution is hypotonic to the cytoplasm of the cell.
