Question
List the steps of preparation of temporary mount of a leaf peel to observe stomata.
Solution
The steps involved in the preparation of temporary leaf mount to view stomata under the light power microscope are following:
1) Remove a healthy leaf from the potted plant.
2) Remove a part of the peel from the lower surface of the leaf. The peel can be removed by folding the leaf over and gently pulling the peel apart using forceps. Place the peel in a watch glass containing water.
3) Put few drops of safranin stain in the watch glass.
4) After 2-3 minutes, approximately take out the peel and place it on a clean glass slide.
