| + | *select a piece of stem of a soft plant. |
| + | *Cut very thin sections of the stem(10 to 20) and place them in a glass dish with water. |
| + | *Select a fine section and transfer it to a glass slide. |
| + | *Add one drop of safranin on the section and a drop of glycerine. |
| + | *Now gently place the cover slip on the slide with the help of dissection needle. |
| + | *Remove the extra stain with the help of blotting paper. |
| + | *Mount the slide on the microscope and observe carefully. |
