Staining Cheek Cells for Microscopic Observation
To observe cheek cells clearly under a microscope, staining is necessary to enhance the contrast and visibility of the cells. Ink is commonly used as a stain for this purpose due to its ability to adhere to the cells and make them more visible.
Reasons for using Ink as a Stain:
- **Adherence**: Ink has a property to stick to the cells, making them easier to visualize.
- **Contrast**: The dark color of ink helps to create a strong contrast against the light-colored cells, aiding in observation.
- **Visualization**: By staining the cells with ink, the details of the cell structure become more apparent under the microscope.
Procedure for Staining Cheek Cells:
1. Collect a sample of cheek cells by gently scraping the inside of the cheek with a swab or toothpick.
2. Place the collected cells on a glass slide.
3. Add a drop of ink to the cells on the slide.
4. Gently mix the cells with the ink using a toothpick or a pipette.
5. Cover the slide with a coverslip and observe the stained cheek cells under a microscope.
By following this staining procedure with ink, the cheek cells become more visible under the microscope, allowing for a better examination of their structure and characteristics.
