Why glycerin is used for mounting a specimen?
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.
Why is glycerine preferred over water to mount a slide with cover slip?
It is used to hold the cover slip in place, not to prevent the glycerin from evaporating. Because the glycerin mountant and polyvinyl alcohol glue stabilizer are both soluble in water, when the glycerin does begin to dry up, the slide is easily soaked or steamed to remove the cover slip, and the specimen remounted.
What is the role of glycerine in the root tip experiment?
Answer: Glycerin prevents the drying up of specimen and also helps in getting a clear picture under the microscopic lens.
What is the purpose of using glycerine as a base?
This medication is used as a moisturizer to treat or prevent dry, rough, scaly, itchy skin and minor skin irritations (e.g., diaper rash, skin burns from radiation therapy). Emollients are substances that soften and moisturize the skin and decrease itching and flaking.
Why is glycerine preferred over water as a mounting material to prepare temporary mount?
It avoids drying of the material.
Why is the staining done prior to mounting?
Explanation: The main reason you stain a specimen before putting it under the microscope is to get a better look at it, but staining does much more than simply highlight the outlines of cells. Some stains can penetrate cell walls and highlight cell components, and this can help scientists visualize metabolic processes.

How does glycerin affect the environment?
“But as with most organic materials, oil and glycerin deplete the oxygen content of water very quickly, and that will suffocate fish and other organisms. And for birds, a vegetable oil spill is just as deadly as a crude oil spill.” That substance turned out to be glycerin from a biodiesel plant.
What is the purpose of adding iodine solution to the specimen?
A small square or circle of thin glass called a coverslip is placed over the specimen. It prevents the slide from drying out when it’s being examined. Iodine stain can be used to stain plant cells to make the internal structures more visible. Most cells are colourless.
What is the purpose of applying stain to a bacterial smear?
Applying a simple stain to a bacterial culture is a technique that is used for examining the size, shape, and arrangement of a specimen. It uses a dye to stain the cells, making them easier to see under a microscope.
