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.

A plant is made up of microscopic living structures called cells. Like animal cells, plant cells have a nucleus and an oily membrane surrounding the whole cell. A plant cell is also encased in a tough cell wall and usually contains a large, fluid-filled bubble called a vacuole. plantâs body has different structures designed for different tasks, such as making food and conserving water. LEAVES, usually broad and flat, take in energy from sunlight and carbon dioxide from the air. ROOTS snake through the soil to take in water and minerals. The STEM supports the part of the plant above ground.
