Answer: Differences in osmotic concentrations

Explanation: With solvent particles flowing into the cell, it means the concentration outside of the cell is higher and with initial volume less than 50%, then that within the cell is lower. This results in an osmotic gradient, allowing particles in areas of higher concentration (outside the cell) to flow into the cell, an area of lower concentration.

When the cell is in a hypotonic solution, the interior of the cell is more concentrated than the exterior. When the cell volume is below 50%, water flows into the cell to reach a dynamic equilibrium.

---------------------------------

If the initial volume of the cell is below 50%, it means that the interior of the cell is more concentrated than the exterior.

      concentration inside the cell  >  concentration outside the cell.

The exterior of the cell represents a solution in which the cell is immersed.

When talking about solutions, we can classify them as follows,

  • Hypertonic ⇒ A hypertonic solution has a higher concentration of solute than the cell. This means that in the cell interior, the solute concentration is lower than in the solution itself.

  • Isotonic ⇒ The solute concentration is the same inside the cell and outside.

  • Hypotonic ⇒ A hypotonic solution has a lower concentration of solute than the cell. This means that in the cell interior, the solute concentration is higher than in the solution itself.

If the initial volume of the cell is below 50%, it means that the cell is in a hypotonic solution.

When a cell is in a hypotonic solution, through osmosis, water moves toward the cell.

Osmosis is the phenomenon that occurs when two dilutions of different concentrations -in this example, the interior of the cell and the solution- are separated by a semipermeable membrane.

The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side to the less diluted one.

Water tends to go from the hypotonic solution to the cell interior and keeps doing so until concentrations are equal in the cell interior and exterior.

This is, the interior and exterior of the cell reach a dynamic equilibrium.

  • Under experimental conditions ⇒ Cells can not limit the amount of water moving into them ⇒ the cell keeps swelling until the membrane can not stretch anymore, and lysis occurs. It bursts.

  • Under natural conditions ⇒ the body regulates the extracellular fluids to avoid cells swelling until they burst ⇒ Dynamic equilibrium ⇒ Homeostasis.

Let us remember that the term homeostasis refers to stability, balance, or equilibrium.

It is the constant interchange of substances between the cells and the intercellular space, until they reach a dynamic equilibrium, despite the constant environmental variations.

So, when the initial volume of the cell is below 50%, solvent particles flow into the cell to maintain homeostasis, which represents a dynamic equilibrium.
