Lentils

Lentils are porous swellings on the stem of plants that facilitate the diffusion of gases. They are formed from cell masses that break through the epidermis.

Lentils are small tumor-like formations on the surface of the stem. They are round or oval in shape and are most often found on the stems of members of the legume family.

Inside the lentils there is loose parenchymal tissue consisting of large thin-walled cells. These cells are formed from the cambium and break through the epidermis of the stem, causing the appearance of lentils. Due to their loose structure, lentils perform a gas exchange function - they facilitate the diffusion of oxygen and carbon dioxide.

Thus, lenticels are important formations on plant stems that participate in gas exchange processes. Their porous structure optimizes the delivery of gases to living cells inside the stem.
