Beside this, What is a cork in biology?

Cork is a protective tissue that separates the living cells of the plant from the outside environment. The formation of cork in the periderm is the result of the activity of a secondary meristem, the cork cambium, or phellogen.

Likewise, What is the main function of cork?

Cork produced by the cork cambium functions as a thick layer of cells that protects the delicate vascular cambium and secondary phloem from mechanical damage, predation, and desiccation. Wood anatomy can be quite complex.

How is cork formed Class 9?

As plants grow older, a strip of secondary meristem replaces the epidermis of the stem. Cells on the outside are cut off from this layer. This forms the several-layer thick cork or the bark of the tree.

Cork cells and sclerenchyma cells are not the same. Cork cells are the part of dermal tissue system and sclerenchyma cells are the part of ground tissue system.

What are the types of Sclerenchyma?

There are two types of sclerenchyma (Figure 4.4): (1) fibers, which are long, very narrow cells with sharply tapering end walls; and (2) sclereids, which are isodiametric to irregular or branched in shape. Fibers function in mechanical support of various organs and tissues, sometimes making up the bulk of the tissue.
