Yes, cheek cells are indeed viewed under a microscope.
Why Are Cheek Cells Examined Under a Microscope?
Cheek cells are a popular choice for microscope observation, especially in biology classrooms, for several key reasons:
- Easy to Obtain: These cells are easily collected with a simple swab of the inner cheek. This non-invasive method makes them readily accessible for study.
- Easy to See: Under a microscope, cheek cells are relatively large and have distinct features, making them straightforward to identify and analyze. This makes them an ideal starting point for learning about animal cell structures.
- Typical Animal Cells: They represent typical animal cells, exhibiting the basic structures common to most cells. This allows for effective learning about cell biology in a practical context.
What Can Be Learned From Cheek Cells Under a Microscope?
Observing cheek cells under a microscope allows for the study of:
- Cell Structure: Key components such as the nucleus, cytoplasm, and cell membrane become visible, offering insights into basic cell anatomy.
- Animal Cell Characteristics: The absence of a cell wall, which is present in plant cells, is one defining feature.
- DNA Research: Cheek cells are useful in extracting DNA for research or identification purposes.
- Paternity tests
- Genetic studies
How Cheek Cells Are Viewed Under A Microscope
The process typically involves:
- Collection: Gently scraping the inside of your cheek with a cotton swab.
- Preparation: Spreading the cells on a slide and applying a stain (like methylene blue) to enhance visibility.
- Observation: Examining the slide under a microscope at different magnifications.
Reference: Cheek cells are easy to obtain and easy to see under a microscope. As such it is a favorite in biology classrooms to show what a typical animal cell looks like. DNA and paternity tests can be done by obtaining these cells and looking at their DNA. (17-May-2017)
