Rachael's Cheek Epithelial Cells

stained with red food colouring!

I currently have a small job with the biology department helping to develop homework labs for first year students taking the online class. Because some of the students are taking the class as distance education, all the materials needs to be items that you can find around home or the grocery store. These cheek cells were harvested with a toothpick and stained with regular red food colouring.

The cells appear quite lucid under the microscope, it's unfortunate the photo does not do them justice.
