Lenticels are portions of the periderm that have numerous pores or intercellular spaces. They appear as raised circular or elongated areas. The dark lines in birch bark and the tiny dots sometimes seen on skin of apples and pears are lenticels.

The initial periderm is interrupted at points around the stem by the occurrence of lenticels (Latin lentis, a lentil). These are blister-like, lenticular breaks in the surface. Most often, a lenticel on a stem forms where a stomate once occurred.

We might expect that the function of lenticels would be interfered with by wetting in the same way as applies to stomata, and it is therefore of interest to find that (at least in young branches, according to Haberlandt) they tend to be developed chiefly on the underside, where they are more or less protected.

These loose areas are extended through the surface of the periderm and are called lenticels. Lenticels function in gas exchange between the air and the stem interior. At the bottom of the deep fissures in tree bark are the lenticels.Â...

The stems of vascular plants have several functions, including support of the plant, transport of water and minerals by the vascular system, and generation of energy ... Openings called lenticels are found along woody stems. Lenticels function as pores to permit the exchange of gases between the stem tissue and surrounding air.
