In both types of feather, the barbules that extend from the barb ramus grow from a single layer of cells, called the barbule plate, on the periphery of the barb ridge.
This wonder material—a form of carbon that comes in films a single atomic layer thick—won Andre Geim and Konstantin Novoselov the Nobel prize for physics last year.
In the uniquely mammalian process of lactation, a special class of milk-secreting cells known as mammocytes line up in a single layer around pear-shaped alveoli.
The endometrium is itself made up of a single layer of simple columnar epithelium, which has ciliated and secretory cells, that sit on top of connective tissue, or stroma.
It's here that oxygen molecules dissolve in the wet mucous, diffuse across the epithelial cells, and then cross the single layer of endothelial cells lining the capillaries to enter the bloodstream.
