What is the function of xylem fibres?

Xylem fibres are specialized cells found within the xylem tissue of vascular plants. Their primary function is to provide mechanical support and structural strength to the plant. Here’s an academically structured explanation, following Google EEAT (Experience, Expertise, Authoritativeness, Trustworthiness) criteria based on reputable sources.

Key Functions of Xylem Fibres

• Mechanical Support:
  Xylem fibres are elongated, lignified (hardened) dead cells that give rigidity and structural support to the plant body, particularly in stems and roots. This helps maintain the plant’s upright posture and stability, especially in large or woody plants.
• Strengthening Vascular Tissue:
  By reinforcing the xylem tissue, these fibres protect delicate water-conducting cells (vessels and tracheids) from physical damage, ensuring the efficient transport of water and minerals.
• Tensile Strength:
  Their thick, lignin-rich cell walls allow them to withstand stretching and bending forces, contributing greatly to the plant’s ability to resist wind and gravitational stress
