Answer 1

Epithelial cells are the large cells those are found in specimen of our gumline which contains nuclei.

Gumline cells are nothing but cheek cells , they have no cell walls and have only a plasma membrane as a result the peptidoglycan layer that gram stains utilise to deferentiate between gram negative & gram positive species of bacteria but human cells are unable to retain the crystal violet introduced in first step of gram stain & gram negative .

Therefore , in gram staining they appear pinkish like gram negative bacteria.
