It also evolves as protective layer near injured parts (wound periderm). Comparing anatomy, chemical composition, and water permeability of suberized organs in five plant species: wax makes the difference. The cells so exposed die and a new periderm arises below them. The periderm forms from the phellogen which serves as a lateral meristem. You seem to have javascript disabled. The activity of the phellogen is more on the outside and thus, the amount of phelloderm formed is generally very small, sometimes restricted only to few layer of cells. But gradually these structures disappear. You are accessing a machine-readable page. Periderm is cork cambium and cork Bark is everything outside the vascular cambium Wood (to a botanist) is secondary xylem Sap wood -still moves water Heart wood -no longer moves water, hardened now used for support the protective tissue on the stems, roots, tubers, and rhizomes of perennial and, less frequently, annual plants; it consists of cork (phellem), phelloderm, and phellogen (cork cambium). The periderm replaces the epidermis and acts as a protective covering like the epidermis. It forms during the radial thickening of plant organs such as stems and roots and replaces the function of primary protective tissues such as the epidermis and the endodermis. Periderm is the corky outer layer of a plant stem formed in secondary thickening or as a response to injury or infection. A wound periderm also forms to heal and protect injured tissues. Periderm is a protective tissue of secondary origin that replaces the epidermal cell layer when the latter is damaged. However, some plant species develope periderm several years after the secondary grow started. Endodermal apoplastic barriers are linked to osmotic tolerance in meso-xerophytic grass. eCollection 2022. Periderm tissue plays a key role in various fruits and vegetables.
