The vascular cambium is the outside cylindrical secondary meristem layer, which later forms the secondary xylem and secondary phloem.

Cork cambium is the layer of parenchyma and collenchyma cells that are derived from the secondary lateral meristem.

What is Vascular cambium?

Definition:

The vascular cambium is the outside cylindrical secondary meristem layer, which later forms the secondary xylem and secondary phloem.

Structure:

The vascular cambium is composed of two cell types. Columnar or long cells are called fusiform initials which are responsible for the vertical growth of the xylem and phloem. Ray initials are cuboidal, smaller cells that are responsible for the horizontal xylem and phloem growth.

Location:

Vascular cambium is found between the primary xylem and primary phloem.

Development:

The vascular cambium originates from the apical meristem.

Function:

Vascular cambium is the vascular conduit inside the plant and it also provides stiffness and structural support to the plant.

Structures produced:

The vascular cambium gives rise to the medullary rays, secondary xylem, and secondary phloem.

What is Cork cambium?

Definition:

Cork cambium is the layer of parenchyma and collenchyma cells that are derived from the secondary lateral meristem.

Structure:

The Cork cambium comprises a single layer of identical cells. These undifferentiated cells later form periderm or the cork cells which are the outermost layer of a trunk. Simply put, cork cambium gives rise to the woody structure of a plant. 

Location:

Cork cambium is found outside the vascular structures of a plant.

Development:

Cork cambium is derived from the secondary lateral meristem.

Function:

Cork cambium helps to retain water and moisture in a plant and gives protection from environmental stresses. It is a tough structure that prevents the microorganisms from invading the plant and causing infection.

Structures produced:

Cork cambium forms the bark and secondary cortex.
