Glycerine is isotonic to the cell sap. Due to this, cells used for mount will not shrink or swell and can be seen in their natural form. Also, glycerine makes the mounted material moist and prevents it from drying out.
Why is glycerine used in cheek cell?
Glycerine is a good dried out agent. It avoids the drying of the specimen. Additionally, glycerine has a tendency to reflect light because of its refractive nature.
Why glycerine 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 glycerin used for mounting of the onion cell or human cheek cell?
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 glycerin is used in preparation of temporary slide?
Answer Expert Verified
Glycerine is an excellent dehydrating agent. It helps to avoid drying of any specimen. Additionally, it reflects lights properly because of its refractive feature.
Why do we use glycerine as mounting medium instead of water?
EXPLANATION: Glycerine also know as glycerol finds its application as a mounting agent. It is best medium to preserve the specimens, slides in container instead of using water as medium to preserve. It also hold coverslip in stable.
What is the use of glycerine in mounting of stained materials on slide?
Answer: The use of glycerine in mounting of stained materials of slides because it is highly dense and has a high refractive index. Explanation: The biological cells require a mounting medium when kept in a glass slide to fix the glass slide; this mounting medium should make the specimen more visible and clear.
Why is glycerine used over safranin while preparing the slide?
Safranin is used to peel off the upper layer of stomata and also to dye the layer purple to see it clearly under the microscope. Glycerine is used to keep the stomata moisturized and wet so that the particle of stomata are easily visible.
Why do we put glycerine on the slide before mounting of the leaf peel *?
We use glycerin before placing the coverslip on the slide, as it helps in not drying the safranin solution on the leaf peel. It helps in keeping the peel moisture.
Why is glycerin used for preparing temporary mount of stomata of a leaf peel?
Role in the preparation of temporary mount of a leaf peel to show stomata: Glycerine: It is a good dehydrating agent and prevents the specimen from drying out. Due to its refractive nature, it tends to reflect the light better and as a consequence, the specimen can be clearly observed under the microscope.
Why do we use glycerine in temporary mount of the material Class 8?
General Science
In the experiment glycerine is used in the temporary Mount to keep it wet . It prevents the material from drying thus keeping it wet.
Why do we use stain for mounting the slide?
STAINS. Stains are used to help identify different types of cells using light microscopes. They give the image more contrast and allow cells to be classified according to their shape (morphology).
