    The secondary meristem, specifically the cork cambium (phellogen), is responsible for cork formation. It arises from the lateral meristem and produces cork cells (phellem) outward and phelloderm inward. Cork cells, once matured, become suberized and die, forming a protective, impermeable outer layer that insulates and protects the plant from environmental stress.

  2. Cork is composed primarily of dead cells filled with suberin. Its structure features tightly packed cells with thick walls, creating a lightweight, flexible, and impermeable material. The cell arrangement forms a honeycomb-like pattern, providing insulation, buoyancy, and protection for the plant.

  3. Suberin in cork cells acts as a hydrophobic barrier, making the cells impermeable to water and gases. This property helps protect the plant from desiccation, pathogens, and physical damage, contributing to the durability and insulation of the cork layer.

    Xylem fibers in vascular tissue provide structural support and strength to the plant. They are elongated, thick-walled cells that reinforce the xylem, enabling it to withstand the tension of water transport. Additionally, they contribute to the overall rigidity and stability of the plant’s vascular system.
