Vedclass · Answer

(A) Lenticels are lens-shaped openings found in the bark of woody stems. During secondary growth,the phellogen (cork cambium) cuts off cells on both sides. The cells cut off towards the outside are called phellem (cork),and the cells cut off towards the inside are called phelloderm (secondary cortex). In the region of lenticels,the phellogen cuts off closely arranged parenchymatous cells towards the outside instead of cork cells. These cells are known as complementary cells. Therefore,complementary cells develop from the phellogen (cork cambium).
