Detailed explanation-1: -Lenticel is a pore in the stem of a woody plant, showing a raised spot that may be filled with a powdery substance. The pore permits air to reach tissue below the surface.

Detailed explanation-2: -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-3: -Stomata are minute holes or apertures in plant tissue that permit gas exchange. Lenticels: A lenticel is a porous tissue found in the periderm of secondary thickening organs, the bark of woody stems, and the roots of dicotyledonous flowering plants. It is made up of cells with vast intercellular spaces.

Detailed explanation-4: -A lenticel is a porous tissue made up of vast intercellular gaps between cells. 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.

Detailed explanation-5: -A lenticel is a porous tissue comprising cells with huge intercellular spaces. They are found in the periderm of secondarily thickened structures, the bark of woody stems, and the roots of dicotyledonous flowering plants.
