Answer 1

Answer:

Answer

To observe the cells in an onion peel, we prepare a slide by adding Glycerin as a mounting agent to the onion peel specimen. Glycerin prevents the drying up of specimen and also helps in getting a clear picture under the microscopic lens. Apart from that, Glycerin also protects the specimen from dust and damage along with preserving the cellular characteristics of the specimen as well as the quality of the stain. Most of these benefits are attributed to the chemical stability of Glycerin.
