You were unable to read the lab manual through the tubes containing hypertonic or isotonic solution because the cells in those solutions remained intact, causing the solutions to be opaque.
- In an isotonic solution, a red blood cell will not experience any net water movement.
- There won't be a net migration of water towards the solution or the cell since the concentration of the solute and water are identical both within and outside the cell.
- An animal or plant cell submerged in a hypertonic solution shrinks as a result of water loss ( water moves from a higher concentration inside the cell to a lower concentration outside ).
- hence the cells remain intact causing the solution to be opaque.
