Final answer:
If you saw large, eukaryotic cells in the prep made from your gumline, they were most likely your own epithelial cells. Epithelial cells are characterized by the polarized distribution of organelles and membrane-bound proteins between their basal and apical surfaces.
Step-by-step explanation:
If you saw large, eukaryotic cells in the prep made from your gumline, they were most likely your own epithelial cells. Epithelial cells are typically characterized by the polarized distribution of organelles and membrane-bound proteins between their basal and apical surfaces. Particular structures found in some epithelial cells are an adaptation to specific functions. Certain organelles are segregated to the basal sides, whereas other organelles and extensions, such as cilia, when present, are on the apical surface.
