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 layerRead more
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.
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.

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.

Xylem and phloem are vital for plant transport. Xylem transports water and dissolved minerals from roots to the rest of the plant, providing structural support with its thick-walled cells. Phloem distributes organic nutrients, primarily sugars, produced during photosynthesis from leaves to growth and storage sites. Together, they maintain the plant’s internal nutrient and water balance, essential for growth and development.
