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.
The mesophyll is the main inner leaf tissue making up the blade of the leaf. Most of the photosynthesis of the plant takes place in the mesophyll. The mesophyll in the upper part of the leaf is made up of tightly packed cells, full of chloroplasts, and is called the palisades layer.The mesophyll in the lower part of the leaves is made up of loosely packed cells and is called the spongy layer.The vascular tissue functions like the circulatory system of the plant. The xylem carries water from the roots to the leaves and to the other upper parts of the plant.he mesophyll in the lower part of the leaves is made up of loosely packed cells and is called the spongy layer.
