Difference Between Cork Cambium and Vascular 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 function of vascular cambium?

The vascular cambium generates the xylem and phloem of the vascular system, which are used for transport and support. It is a single layer of meristematic cells that undergoes an expansion during the transition from primary to secondary growth.

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 produces the cork cambium?

lateral (nonapical) meristem, called the cork cambium, develops in some of the cells of the older phloem and forms cork cells. The cork cells push the old secondary phloem cells toward the outer margins of the stem, where they are crushed, are torn, and eventually slough off. All tissues outside…

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.

Where is vascular cambium found?

The vascular cambium is the main growth tissue in the stems and roots of many plants, specifically in dicots such as buttercups and oak trees, gymnosperms such as pine trees, as well as in certain vascular plants. It produces secondary xylem inwards, towards the pith, and secondary phloem outwards, towards the bark.

What gives rise to vascular cambium?

In woody roots the vascular cambium (the lateral meristem that gives rise to secondary phloem and secondary xylem) originates in the pericycle as well as in the procambium; the procambium is the primary meristematic tissue between the primary phloem and xylem.

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.

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.
