Why you use a drop of water in preparing microscopic slide?
A drop of water is used to create a thin film of liquid on the slide, which helps to spread and suspend the specimen evenly for viewing under the microscope. It also prevents the specimen from drying out during observation.
When viewing a slide under oil immersion it is best to use which objective?
When viewing a slide under oil immersion, it is best to use the 100x objective lens. This high-power lens allows for greater magnification and resolution, making it ideal for observing fine details in the specimen. The use of immersion oil helps to reduce refraction of light and improves image clarity by providing a medium with a similar refractive index to glass.
What is the use of glass slide?
The glass slide has allowed a closer, more in-depth look into the world around us, from pond water to pap smears. Skin scrapings, blood smears, hair, parasites, tissue samples and the like have all found their way between a glass slide and a cover slip at one time or other. ~Karl
Can you use iodine solution instead of methylene blue in cheek cell slide?
Yes, you can use iodine solution instead of methylene blue to stain cheek cells. Iodine primarily stains carbohydrates, highlighting certain cellular structures like nuclei and providing contrast. However, methylene blue is a general stain that can better enhance the visibility of cellular details, such as the nucleus and cytoplasm. While both stains can be used, methylene blue may offer clearer results for observing cheek cells.
What does the microscope rest on?
In compound microscopes for use for viewing thin sections at high power, specimens are mounted on a microscope slide and covered with a coverslip and are placed on the microscope stage or base plate. In stereomicroscopes the same is done however for large objects such as rocks or minerals no microscope slide is required the object to be observed is placed directly on the stage.

Why is it important to use sharp cutting blade when preparing temporary slide?
For penetration of light into the cell
What is the function of rehearse timing in Microsoft Office Power Point?
it is use for preparing your speech with your slide.
Why do you use iodine to help make a slide for a microscope?
Iodine is used to stain cells on a microscope slide to make them more visible under the microscope. It helps to highlight specific structures within the cells, making them easier to study and identify.
What should be observed or avoided in preparing strong iodine solution?
Observations: Ensure the iodine crystals dissolve completely in the solvent. The solution should be clear and free of any solid particles. Avoid: Do not inhale iodine vapor as it can be harmful. Use gloves and goggles to protect from irritation.
How does a microscope use light?
Microscopes use light to illuminate the stage where you place a slide for viewing. Without this light, you would be unable to see much of anything.
How do you secure the slide to the microscope?
To secure the slide to the microscope, place the slide on the stage and then use the mechanical stage controls to move the slide into the desired position. Once the slide is in place, carefully lower the stage clips to secure the slide in position. Make sure the slide is flat without any bubbles or wrinkles before viewing.
Use of glass slide?
Glass slides are commonly used in laboratories to hold thin samples, such as tissue sections or blood smears, for viewing under a microscope. The smooth, flat surface of the glass slide provides a stable platform for the sample and allows light to pass through, enhancing the visibility of the specimen. Glass slides are also used for preparing and staining samples to enhance contrast and improve the visualization of specific structures.
What magnification should you use to begin viewing a slide?
The lowest magnifiction, some microscopes are different but ours start at 40X

The use of immersion oil helps to reduce refraction of light and improves image clarity by providing a medium with a similar refractive index to glass.
Why use iodine on onion slide?
Iodine is used on onion slides to stain the cells so that the nucleus becomes more visible under a microscope. This staining technique helps enhance the contrast between the different cellular structures, making it easier to observe and study them.
How do you pick up onion epidermis?
To pick up onion epidermis, you use forceps to pick it up, and afterwards, to see the cells, you would use a clean slide, iodine and a cover slid. Hope that helped!
