Detailed explanation-1: -Lenticels are porous tissue consisting of cells with large intercellular spaces in the periderm(outermost layers of stems and roots of woody plants). It functions as a pore and a pathway for gas exchange (respiration). It is similar to stomata but stomata usually works at day time whereas lenticels works at night.

Detailed explanation-2: -Lenticels are loosely packed dead cells that allow gaseous exchange in plants. They are present in a small area in the bark. Lenticels allow oxygen to pass to the intracellular spaces and carbon dioxide is liberated, therefore completing the process of respiration.

Detailed explanation-3: -Respiration in Stem To breathe, the air in a stem diffuses into the stomata and travels through various regions of the cell. The released carbon dioxide is distributed through the stomata at this time. In higher or woodier plants, lenticels are known to perform the gaseous exchange.

Detailed explanation-4: -The lenticels found on the epidermis of different plant organs (stem, petiole, fruits) made up of parenchymatous cells are pores that always remain open, in contrast to stomata, which regulate their extent of opening. Lenticels are visible on fruit surfaces, such as mango, apple, and avocado.

Detailed explanation-5: -On stems and roots, lenticels appear as elevated circular, oval, or elongated patches. Lenticels allow gases to pass between the atmosphere and the organs’ interior tissues.
