How do you look at cheek cells under a microscope?
- Get a dry microscope slide and cover slip.
- Put a drop of methylene blue on the slide.
- Gently scrape the inside of your cheek with a toothpick and swirl it in the dye on the slide.
- Place a cover slip on the suspension and view at 1000X total magnification.
What did the cheek cells look like?
This human cheekcell is a good example of a typical animal cell. It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape. Like most eukaryotic cells, this cell is very large compared to prokaryotic cells.
How do you observe cheek cells?
- Take a clean cotton swab and gently scrape the inside of your mouth.
- Smear the cotton swab on the centre of the microscope slide for 2 to 3 seconds.
- Add a drop of methylene blue solution and place a coverslip on top.
- Remove any excess solution by allowing a paper towel to touch one side of the coverslip.
How are cells examined under a microscope?
Two types of electron microscopy—transmission and scanning—are widely used to study cells. In principle, transmission electron microscopy is similar to the observation of stained cells with the bright-field light microscope.
How do your cheek cells look like how are they arranged?
The cheek cell, an example of an animal cell, generally has a circular, oval shape. Due to the fact that the cheekcell was not in groups or clumps, the arrangement of this type of cell is unknown. From previous labs, the cells were pushed together completely; each cell fitted beside another cell perfectly, and so on.
How can you see cheek cells under a microscope?
The nucleus at the central part of the cheekcell contains DNA. When a drop of methylene blue is introduced, the nucleus is stained, which makes it stand out and be clearly seen under the microscope.
What do we observe in human cheek cell?
The cell has different parts, and those that can absorb stains or dyes are referred to as chromatic. The nucleus at the central part of the cheekcell contains DNA. When a drop of methylene blue is introduced, the nucleus is stained, which makes it stand out and be clearly seen under the microscope.

What did you see when you looked at the cheek cells?
Cheek cells are fairly easy to observe, simply take a flat toothpick and rub it on the inside of the cheek. They can be seen faintly even at 40x (scanning power), but the most dramatic images are at 400x where the nucleus is clearly visible as a dark spot in the center of the cell.
Can you see human cells in microscope?
Microscopes provide magnification that allows people to see individual cells and single-celled organisms such as bacteria and other microorganisms. Types of cells that can be viewed under a basic compound microscope include cork cells, plant cells and even human cells scraped from the inside of the cheek.
What parts of the cheekcell are visible under a microscope?
Cheek cells can be easily obtained by gently scraping the inside of the mouth using a clean, sterile cotton swab. Once the cells have been obtained, the following procedure is used for cheekcell wet mount preparation: place a drop of physiological saline on a clean microscopic slide (central part of the slide)
What are epithelial cheek cells?
The tissue that lines the inside of the mouth is known as the basal mucosa and is composed of squamous epithelial cells. These structures, commonly thought of as cheek cells, divide approximately every 24 hours and are constantly shed from the body.
