Question

Why do solvent particles flow into the cell when the initial volume is below 50%?

Answer 1

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.

Answer 2

Osmotic concentration differences

When solvent particles flow into the cell, the concentration outside the cell is higher, and when the initial volume is less than 50%, the concentration inside the cell is lower. This creates an osmotic gradient, allowing particles from higher concentration areas (outside the cell) to flow into the cell, which has a lower concentration area.

The rate of osmosis over time is affected by the concentration of a solute, with the higher the concentration, the faster the rate of osmosis.
