Answer:
i. Lenticels are lens-shaped openings on epidermis, through which gaseous exchange takes place.
ii. Cork cells are with deposition of suberin in the cell wall which makes them impervious to air and water.
iii. Due to this, at certain regions, the cork cambium cuts off loosely arranged parenchymatous cells, which then rupture the epidermis and forms openings called lenticels.
