What is pith in biology?

Published in Plant Anatomy 2 mins read

Pith, also known as medulla, is a central tissue found within the stems of vascular plants. Let's explore this plant tissue in more detail:

Pith: The Core Tissue of Vascular Plants

Pith is a crucial component of the plant's vascular system, acting as a central hub for nutrient storage and transportation.

Composition and Function

  • Composition: Pith consists primarily of soft, spongy parenchyma cells. According to the provided reference, these cells are responsible for storing and transporting nutrients throughout the plant.
  • Function: The primary function of pith is nutrient storage and transport. This helps sustain the plant's metabolic activities and growth.

Location

  • Eudicots: In eudicots, pith is located in the very center of the stem, forming a central core.
  • Monocots: In monocots, the pith extends beyond the stem and can also be found in flowering stems and roots.
