lenticel




A small raised pore, usually elliptical in shape, which develops in woody steams when epidermis is replaced by cork. Lenticels are packed with loosely arranged cells and comprise spongy areas in the cork surfaces of stems, roots, and other plant parts that allow the exchange of gases between internal tissues and the atmosphere through the periderm.
