Apply a small piece of blotting or tissue paper on the edge of the cover slip to remove the water. 6. Place a drop of 0.5 saline solution on the slide, close to but not on the cover slip. 7. Draw the solution out under the cover slip by applying again a small piece of tissue paper to the opposite edge. 8. Examine under the HPO and observe the changes in the guard cells. 9. Repeat procedure numbers 6 to 8, but this time, use the 0.9 saline solution, after which 1.5 saline solution follows. 10. Fill up the table and draw the following: a. guard cell in distilled water b. guard cell in 0.5 saline solution c. guard cell in 0.9 saline solution d. guard cell in 1.5 saline solution
