Answer» ls are large sized aerating pores PRESENT in the cork tissue for gaseous exchange. They occur in almost all types of phellem containing organs including STEM, root, potato tuber ETC. They are slightly raised spots on the surface of stem. They help in exchange of gases.It functions as a pore, PROVIDING a pathway for the direct exchange of gases between theinternal tissues and atmosphere through the bark, which is otherwise IMPERMEABLE to gases. The name lenticel, pronounced with an [s], derives from its lenticular (lens-like) shape. |
