Detailed explanation-1: -Pith, or medulla, is a tissue in the stems of vascular plants. Pith is composed of soft, spongy parenchyma cells, which in some cases can store starch. In eudicotyledons, pith is located in the center of the stem. In monocotyledons, it extends also into flowering stems and roots.
Detailed explanation-2: -The pith is a small zone at the center of the stem, consisting of parenchyma cells and originating as a primary tissue from the ground meristem.
