Option c) Lenticels are opening in the bark.
- Lenticels are present in the epidermis layer of the parts which have secondary growth like the bark. They are shaped like a lens, hence the name lenticel.
- They are openings on the bark allowing the exchange of oxygen and carbon dioxide.
- Due to the thickening of secondary structures by lignin, oxygen and carbon dioxide is unable to reach these parts.
- Lentils serve the purpose of providing gases to impermeable regions.
