Pith, or medulla, is a tissue in the stems of vascular plants. Pith is composed of soft, spongy parenchyma cells, which store and transport nutrients throughout the plant. In eudicots, pith is located in the center of the stem.In monocots, it extends also into flowering stems and roots.The pith is encircled by a ring of xylem; the xylem, in turn, is encircled by a ring of phloem.ith is composed of soft, spongy parenchyma cells, which store and transport nutrients throughout the plant. In eudicots, pith is located in the center of the stem.
Dermal Tissue System: The dermal tissue system makes up the outside covering of the plant. This system consists of the epidermis and the periderm. Epidermis: The epidermis consists of a single layer of cells that covers the majority of young plants.The epidermis is present throughout the life of plants that exhibit only primary growth. Primary growth refers to cells and tissues that originate from the apical meristems.arenchyma Tissue: The most abundant, diverse, and versatile cells in a plant are found in the parenchyma tissue. Parenchyma cells have thin cell walls, and their structure is somewhat non-descript, but tend to be more or less isodiametric (equal diameters in all directions).
