Difference Between Vascular Cambium and Cork Cambium

The cork cambium originates from the secondary lateral meristem while the vascular cambium originates from the apical meristem. The cork cambium gives rise to the bark and the secondary cortex. The vascular cambium gives rise to the secondary xylem and secondary phloem.

What is cork cambium and its role?

The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. ... The function of cork cambium is to produce the cork, a tough protective material. Synonyms for cork cambium are bark cambium, pericambium and phellogen.

What is the difference between Cork and bark?

Cork and bark are two outer components of woody plants. Bark is composed of cork, cork cambium, phelloderm, cortex, and the secondary phloem. ... The main difference between cork and bark is their structure and function. Cork serves as a protective barrier whereas bark has other functions such as storage and transport.

What is the name of cork cambium?

cambium, called the phellogen or cork cambium, is the source of the periderm, a protective tissue that replaces the epidermis when the secondary growth displaces, and ultimately destroys, the epidermis of the primary plant body.

What forms the cork cambium?

Cork cambium arises from dedifferentiation of parenchyma or collenchyma cells located at the outermost layer of the cortex, after the secondary xylem and phloem formation is started. Sometimes, the first meristematic cells are differentiated from primary phloem or from the epidermis.

What is the main function of cork cell?

The walls of cork cells contain a chemical called suberin, which makes them impermeable to water and gases. Thus, cork cells prevent water loss from plants and also make them more resistant to bacterial and fungal infection.

What is the role of cork?

Function:The main function of cork is to avoid water loss. The thick material of cork makes it hard or water molecules to pass through it and it also protect the plant from mechanical injuries and infections.

Is a cork a living thing?

A mature cork cell is non-living and has cell walls that are composed of a waxy substance that is highly impermeable to gases and water called suberin.

What is difference between Cork and cortex?

Cork (phellem) is the outermost tissue of the bark, which is impermeable to water and gases. ... Cortex is a primary tissue in both stem and root and is located between the non-living epidermal layer and the secondary phloem. Secondary phloem is produced by the vascular cambium.

Is bark alive or dead?

The outer bark, which is mostly dead tissue, is the product of the cork cambium (phellogen). Layered outer bark, containing cork and old, dead phloem, is known as rhytidome.

What is the other name of cork?

Cork tissue is also known as phellem. Cork cells are dead when mature and hence form the outer layer in stems and roots of woody plants. They are impermeable to water and gases.

What is Phellem?

1. phellem - (botany) outer tissue of bark; a protective layer of dead cells. cork. phytology, botany - the branch of biology that studies plants. bark - tough protective covering of the woody stems and roots of trees and other woody plants.

How are cork cells formed?

Cork is the outer protective layer of trees.It is a part of bark.As plants grow older the outer protective tissues undergoes certain changes. The epidermis of the stem is replaced by secondary Meristem. This forms the several thick layers of cork. ... Cork cells are dead.
