Summary
[edit]DescriptionWoody Dicot Stem Lenticel Formation in Liriodendron (36584602711).jpg |
cross section: Sambucus stem magnification: 400x During the first year of growth the underling activity of the cork cambium begins to replace the cutinized epidermis and outer cortical tissues with a protective layer of cork rich periderm. The outermost layer of periderm consists of layers of cork cells, the phellem, which produce the waterproofing substance suberin. Cork cells are dead at maturity. Deep to the phellem is a layer of living cork cambium or phellogen and just beneath that layers of cork parenchyma or phelloderm. Many cells in the periderm contain dark staining tannins.Deep to the periderm is a narrow cortex of parenchyma cells. |
