Question

what is difference between cork and bark ?

Answer 1

Comparison of cork and bark. Differences: (a) Cork is composed of corky cells and bark may consist of cork only or alternating layers of cork and dead cortex or phloem tissue. (b) Cork commonly occurs in young roots and stems, while bark occurs on older stems and roots.

Answer 2

Cork: Cork refers to the tough elastic tissue of plants in the outer layer of the bark of a tree.

Bark: Bark refers to the outermost covering of the trunk and root of a plant.


Cork: Cork is a component of the bark.

Bark: Bark consists of cork, cork cambium, phelloderm, cortex, and secondary phloem.


Cork: Cork is formed from the cork cambium.

Bark: Bark is formed from both cork cambium and vascular cambium.


Cork: Cork consists of dead cells.

Bark: Only the secondary phloem consists of live cells.


Cork: Cork protects the shoot and root from water loss.

Bark: Bark has storage, protective, and transport functions.

Cork and bark are two outer components of woody plants. Bark is composed of cork, cork cambium, phelloderm, cortex, and the secondary phloem. Therefore, cork is a component of the bark. 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.
