Except in the very youngest regions, the stems and roots of woody plants (specifically, gymnosperms and dicotyledons) are covered by bark consisting of the functional secondary phloem and rhytidome, a complex tissue comprised of successively formed periderms, often of overlapping shell-like morphology, between which . The suberin, a fatty substance, generally occurs as a distinct lamella that covers the original primary cellulose wall. In this article we will discuss about the interxylary periderm in plants, explained with the help of suitable diagrams. Making stems and roots thicker rather than longer involves quite different process Secondary growth in plants are produce by lateral meristems Instead of growth in length, secondary growth is radial- increasing the diameter of a stem or root as dividing cell produce lateral or sideways growth In lateral meristem, new cells . A Feature We have compared, The periderm is a corky tissue that replaces the epidermis when the latter is damaged, and is critical for preventing pathogen invasion and water loss. The wound periderm is similar to normal periderm in origin and cellular structure. The cell wall structures distinguish these tissues. This site needs JavaScript to work properly. Phloem is composed of 5-6 layers and is Thus, characterizing the potato periderm contributes to modeling cork development in plants and helps to resolve critical agricultural problems. The periderm is the layer of the bark that is exposed to the environment. At the time of the beginning of the development of a phellogen in epidermal cells, the protoplast loses central vacuoles and the cytoplasm increases in amount and becomes more richly granular.
