A lenticel is a porous tissue made up of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of dicotyledons flowering plants.
The tiny pores which are elliptical in shape are lenticels.
These are developed from woody stems when the epidermis is substituted by the bark or cork.
On young branches, lenticels appear as cork-like rough structures in the woody plant.
The porous tissues under the lenticels can generate many intercellular spaces between cells.
The tissue occupies the lenticels and they appear from the cell division of substomatal ground tissue.
The formation begins during the development of the periderm.
