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.
Xylem. Xylem is tough, woody tissue that transports water and minerals from the roots of the plant to the stem and leaves. Flowering plants develop xylem vessels, cylindrical cells stacked end-to-end.When the plant matures, the ends of the cells disintegrate and the cell contents die, leaving long non-living tubes.lants turn sunlight into sugar in their leaves, while their roots extract water and minerals from the soil. But these valuable products must be transported throughout the plant in order for it to survive.
