6. If a cell contains 85% water and is placed into a environment which is 50% water. Is the cell hypotonic or hypertonic? In which direction will the water move, into the cell or out of the cell?

7. A cell contains 85% water and is placed into a solution which contains 90% water. Is the solution in the environment hypotonic or hypertonic? In which direction will the water move?

8. If a cell which contains 90% water is placed into an isotonic solution, what percentage of the solution is water?

9. A cell contains 95% water, the environment outside the cell contains 45% solutes. Is the cell in a hypotonic or hypertonic environment?

10. A cell containing 25% solutes is placed into a solution which contains 35% solutes. Which direction will the water move, into the cell or out of the cell?

11. A plant cell containing 95% water is placed into a 10% salt solution. Is the salt solution hypotonic or hypertonic? Which direction will the water move?

 

12. If water leaves a cell when placed into a solution, is the cell hypotonic or hypertonic
