Question

List the characteristics of cork how much are they formed mention their role

Answer 1

Cork is a substance which comes from the bark of a tree. As the plants grow older protective tissue undergoes certain changes. A strip of secondary moisten called cork cambium replaces the epidermis of the stem. Cork cambium is a simple tissue, the cells are rectangular and their protoplast are vacuolated and certain tannins and chloroplasts.
Cork cambium gives off new cells on its both sides,thus forming cork on the outer side and the secondary cortex or phelloderm on the inner side. The walls of the cork cells are heavily thickened with a organic substance.
Cork is used as insulators, shock-absorbers
