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.
1 Sclerenchyma tissues are thick-walled support cells found throughout the plant as fiber. 2  Xylem is a structurally complex tissue that conducts water and nutrients from the roots to all parts of the plant. 3  The xylem is comprised of a series of long tubes made up of shorter vessel members.
