Question

Which statement about an isotonic solution is correct? * 7 points The solution has the same solute concentration as the cell. The solution has a higher solute concentration than the cell. A cell in the solution will lose water. A cell in the solution will gain water.

Answer 1

The solution has the same solute concentration as the cell.

Step-by-step explanation:

Tonicity of a solution refers to the ability for a solution to direct the flow of water into or out of a cell via osmotic process. Based on this, a solution can either be hypertonic, hypotonic and isotonic.

- A hypertonic solution is a solution in which the solute concentration is high in relation with that of an intracellular solution. Hence, water moves out of the cell.

- A hypotonic solution is a solution which solute concentration is low in relation to that of an intracellular solution. Hence, water moves into the cell.

- An ISOTONIC solution is a solution that has the same solute concentration as that of an intracellular environment i.e. equal solute concentration. There is a net water movement
