Question

18. If the inside & outside of a cell are both isotonic, does water still
move across the cell membrane? Explain.

Answer 1

In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. There is no net water movement, so there is no change in the size of the cell
