What are lenticels in botany?

Answer: A lenticel is a highly permeable tissue composed of large cell membrane gaps. Lenticels enable gas to escape between both the environment and the internal connective tissue of the organ systems. Lenticels appear as raised circular or enlarged spots on roots & stems.

• They support evaporation and transpiration as well as groundwater uptake in order to maintain and improve a consistent movement of air between both the plant as well as the environment.
• Lenticels can be found on the areas of the skin of fresh-faced or lignified cells, such as root systems, stems, and fruits. These are also found in shrubs and trees, such as cork, which covers established tree exteriors.
