Question

Which of the following statements about an isotonic solution and a cell is correct?

A) The solution has the same solute concentration as the cytoplasm does.

B) A cell in the solution will gain water.

C) A cell in the solution will lose water.

D) The solution has a higher solute concentration than the cytoplasm does.

Answer 1

In an isotonic solution, the concentration of solute in the solution is equal to the concentration of solute in cells. In a hypotonic solution, the concentration of solute in the solution is less than the concentration of solute in cells, causing water to flow into the cell. B) A cell in the solution will gain water

Step-by-step explanation:

B. The concentration of solute in the solution can be equal to the concentration of solute in cells. In this situation, the cell is in an isotonic solution (iso = equal or the same as normal). The amount of water entering the cell is the same as the amount leaving the cell.

C. The concentration of solute in the solution can be less than the concentration of solute in the cells. This cell is in a hypotonic solution (hypo= less than normal). The net flow of water will be into the cell.
