Safranin: It stains the lignin and suberin and other plant materials easily. It imparts a red colour to the cells and tissues, thereby highlighting them when seen under the microscope.
Which stain is used in preparing a temporary mount of stomata?
Answer Expert Verified
The correct answer is the option C – Safranin. Safranin is used as the stain while preparing a temporary mount of the stomata in a leaf peel. The leaf peel is carefully peeled off and left in the safranin dye for 2 – 3 minutes, after which it is mounted using glycerin.
Which stain is used for temporary mounting of root and leaf *?
So, the correct answer is Safranin.
Why is glycerine used for preparing a temporary mount?
Glycerine is used to make the temporary mount of a peel. Glycerine is used for this purpose because it is a perfect dehydrating agent and prevents the specimen from drying out.
What are the stains that are generally used when we prepare a temporary mount of a slide?
Common fixatives include formaldehyde, ethanol, methanol, and/or picric acid. Mounting – involves attaching samples to a glass microscope slide for observation and analysis.
Why is safranin used for staining leaf peel?
Safranin: It stains the lignin and suberin and other plant materials easily. It imparts a red colour to the cells and tissues, thereby highlighting them when seen under the microscope.
What are temporary mounts?
Wet mount or temporary mount:
Wet mount or temporary mount technique is used to study the movement and behavior of living microorganisms. In this method, a drop of water is placed over a slide and then the specimen is placed within it. After that covers it with a coverslip and observe under a microscope.

Why is the temporary mount slide mounted in glycerine a stain the material B prevents drying only C provide support to cell D to keep cell alive?
In the experiment, glycerine is used in the temporary mount to keep it wet. Option ‘a’ is correct. It prevents the material from drying thus keeping it wet. While carrying out the onion peel experiment or cheek experiment, glycerine is an important component which gives pretty clear reading while keeping it wet.
What is the use of safranin and glycerine?
Glycerine is used to keep the stomata moisturized and wet while safranin is to stain/dye the layer purple to see it clearly under the microscope.
Why glycerine is used in preparation?
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. It expels bubbles which may come during the mounting of the slide.
Why safranin is used to stain plant cells?
Why is safranin convenient to stain plant cells whereas a methylene blue solution is convenient for animal cells? The safranin stain is a cheaper and safer-lab stain, and also provide a strong contrast to the crystal violet, which allows easy and rapid detection of the plant’s vascular tissue.
What is the use of safranin solution?
Safranin is used as a counterstain in some staining protocols, colouring cell nuclei red. This is the classic counterstain in both Gram stains and endospore staining. It can also be used for the detection of cartilage, mucin and mast cell granules.
What is the purpose of staining wood?
The primary purpose of stain is to color wood, while offering certain protections as a result of the coloring and absorption of the stain deep into the wood. Perhaps the most common reason to use stain as protection is against ultraviolet light.
What is the function of safranin how did you use it in the experiment?
The safranin is used in the agreement because the safranin is used to peel the stomata and the glycerine which is used in that experiment which helps to keep the stomata wet so that the stomata can be easily visible and the particles of the stomata can be very much visible for the experiment.
Why preparing a temporary stained mount of a leaf epidermal peel the extra stain is removed by?
Extra stain is removed by using cotton wool, when preparing temporary stained mount of a leaf epidermal peel. Explanation: If we wash the prepared slide with water, the entire content of the slide may get damaged due to the entry of water inside it.
How can you prepare a temporary mount of a specimen?
In the watch glass, stain the sample by adding some drops of safranin through a dropper. Add a drop of glycerin on the peel. Put a clear coverslip over it gently using a needle. Examine the slide first under a low-power and then under a high-power magnification of a compound microscope.
How would you prepare a temporary mount of a specimen for light microscopy?
To prepare the slide:
- Place a drop of fluid in the center of the slide.
- Position sample on liquid, using tweezers.
- At an angle, place one side of the cover slip against the slide making contact with outer edge of the liquid drop.
- Lower the cover slowly, avoiding air bubbles.
- Remove excess water with the paper towel.
What is temporary mount of plant tissue?
Glycerin- Jelly substance used in the mounting of tissues because it keeps specimens free from moisture and other contaminants and because of its high refractive index.
Which stain is used while preparing a temporary mount of onion peel cells?
saffranine
For preparing a temporary mount of the onion, the dye used is saffranine. Saffranine is extensively used in cytology. It will stain the cell nuclei red.
Which stain is used for mounting of cell division in onion cells?
According to the question, the stain used in onion root cells is acetocarmine as it stains the nucleus and helps in viewing different stages of mitosis.
