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.
Why glycerine is used as a mounting reagent give reason?
It avoids the drying of the specimen. Besides, glycerine tends to reflect light due to its refractive nature. As a result of it, image appears clearer under the microscope. Due to these reasons, glycerine is used while preparing temporary mount of leaf peel.

What is the role of glycerine in onion experiment?
Glycerin is considered as a mounting agent while making a slide of onion peel. It is a good hydrating agent. It does not allow the specimen to dry out during the long duration of study. It provides a wet medium for the stain so the cell structure can be easily studied.
Why onion peel is kept in glycerine and covered by a cover slip?
Answer: Explanation: Glycerine prevents the onion peel from drying up by cutting contact from the atmosphere while coverslip prevents the lens of the microscope to come in contact with the specimen.
