Vedclass · Answer

(A) Lenticels are small,lens-shaped openings or pores present on the surface of the bark of woody stems and roots.They are formed due to the activity of the phellogen (cork cambium) which produces loosely arranged parenchymatous cells called complementary cells instead of cork cells at certain regions.These pores allow for the exchange of gases between the internal tissues of the stem and the outer atmosphere,thus acting as aerating pores.
