Preparing a Microscope Slide

1. Place your specimen in the middle of a clean slide. Ensure that the specimen is laying flat and not folded over on itself.
2. Add 2-3 drops of the stain solution. Plant cells are commonly stained with iodine, whereas animal cells are commonly stained with methylene blue. Both of these solutions stain the nucleus of each cell and your fingers and clothes, so be careful.
3. Holding a coverslip by its edges in your left hand, manoeuvre it so that the bottom edge of the coverslip makes contact with both the slide and the edge of the stain solution. With your right hand, support the top edge of the coverslip with a pair of tweezers.
4. Gently lower the coverslip with the tweezers, ensuring that no air bubbles are trapped under the coverslip.
5. Place your slide on the microscope stage and examine it under low power magnification.

In a plant, I see this cell wells it look like a honeycomb.

In human saliva, I see cells the cells look like a black cloud.
