Pith is the central idea or essence of something.

In botanical terminology, pith refers to a spongy, central cylinder of tissue found inside the stems of most flowering plants.

Origin of the word Pitch

The word comes from the Old English word piþa, meaning substance, akin to Middle Dutch Pitt, meaning the pit of a fruit.

Functions of Pitch

  • 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.
