What is the difference between lenticels and stomata ?

Explanation

Lenticels: Lens shaped openings in the cork of woody trees ar called lenticels. They show closely arranged parenchymatous cells. The lenticels permit the exchanges of gases between the outer atmosphere and the internal tissues of the woody organs. There is no opening and closing mechanism.
Stomata: Stomata are present in the upper epidermis and lower epidermis of leaves. They help in exchange of gases. In dicot leaves, on either side of stomata kidney shaped guard cells are present. In monocot leaves, dumbbell shaped guard cells are present. Guard cell contains chloroplast They help in opening and closing of stomata. Stomata helps in the gaseous exchange and also promote transpiration.
