DENDROLOGY

Detailed explanation-1: -The air in case of stem diffuses into the stomata and moves through different parts of the cell to respire. During this stage, the carbon dioxide liberated is also diffused through the stomata. Lenticels are known to perform gaseous exchange in woody or higher plants.

Detailed explanation-2: -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-3: -Lenticels are the special inlets present in the stem of woody plants that ensures the intake of oxygen from the atmosphere. Therefore, the intake of oxygen by lenticels directly affects the process of respiration.
