10 Key Difference between Cork Cambium and Vascular Cambium with Table

What is the difference between cork cambium and vascular cambium?

Dicot plants have both cork and vascular cambium. These tissues are responsible for secondary growth in woody plants.

The core difference between cork cambium and vascular cambium is that cork cambium produces both cork and secondary cortex while vascular cambium produces secondary xylem and secondary phloem.

Difference between Cork Cambium and Vascular Cambium

What Is a Cork Cambium?

Cork cambium is a layer beneath the epidermis and it is formed from the secondary meristem cells. The cambium comprises of parenchyma and collenchyma cells.

Characteristics of Cork Cambium

Actively dividing cells

Produce fatty substances

Has pores for exchange of gases

Cork cells tend to be dead cells

What Is a Vascular Cambium?

Vascular cambium is responsible for giving rise to secondary phloem and secondary xylem. It has a cylindrical secondary lateral meristem.

Characteristics of Vascular Cambium

Secondary xylem occurs inside the cambium ring and secondary phloem on the outside

Activities of the cambium are influenced by season

Produce an annual ring in the stem

Comparison Chart: Cork Cambium vs Vascular Cambium

Basic Terms	Cork Cambium	Vascular Cambium
Meaning	It is the lateral ring of the meristematic tissue in woody plants	It is the cylindrical layer of meristematic tissue found between the primary xylem and primary phloem.
Development	Formed from the secondary lateral meristem	Formed from the apical meristem.
Location	Outside the vascular tissue	Occur between the primary xylem and primary phloem.
Produce	Give rise to the secondary cortex and bark	Give rise to secondary xylem and secondary phloem.
Other Structures	Produce lenticels	Produce medullary ray
Main role	Offer protection against physical damage and prevents water loss.	Produce vascular tissue to help the conduction inside the plant and provides structural support to the plant.

Core Difference between Cork Cambium and Vascular Cambium In Point Form

Cork cambium is also known as phellogen while vascular cambium as cambium

Cork cambium offers protection against mechanical damage and prevents water loss while vascular cambium produce vascular tissue for structural support and water conduction in the plant

Cork cambium produces lenticels while vascular cambium produces a medullary ray

The cork cambium gives rise to the secondary cortex and bark while vascular cambium gives rise to secondary xylem and phloem

Cork cambium occur on the outside the vascular tissue while vascular cambium occur between secondary xylem and phloem

Cork cambium is derived from the secondary lateral meristem while vascular cambium is derived from apex meristem

Cork cambium inner derivative is the secondary xylem while that of vascular cambium is the phelloderm

The peripheral derivative of vascular cambium is phellem while that of cork cambium is the secondary phloem

Cork cambium cells are arranged as stratified manner while those of vascular cambium is in a non-stratified or stratified manner.

The shape of cork cambium is rectangular or polygonal while that of vascular cambium is spindle-shaped or cuboidal.

Similarities between Cork Cambium and Vascular Cambium

Both promote secondary growth in stems and roots

Both originated from meristematic tissues

Both have cylindrical rings

Both have actively dividing cells

Both provide protection and structural support to the plant

Both are present in dicot plants
