When conditions are right -- there is appropriate light and water -- the seed coat may trigger the germination of the seed.
When a great deal of xylem accumulates, it is called wood; plants with wood may be trees, shrubs, or stout vines. Periderm is the other product of secondary growth; it is produced by the cork cambium, a cylindrical layer of cells which develops not far under the outer skin (epidermis) of the plant.his layer may be thick or thin, depending on the species, but it often contains light-sensitive chemicals.
