प्रश्न
What is the commercial source of cork? How is it formed in the plant?
उत्तर
The commercial source of cork is the cork tissue of Quercus suber. Cork cambium or phellogen cells are used to form cork. Then phellogen cells divide periclinal; cutting cells towards the inside and outside. The cells which are cut off towards the outside become suberised and dead and form cork.
