Each organ of plant exchange gases , leaves exchange gases by stomata , roots through diffusion of gases present in soil and plants with green stems exchange gases through stomato present on their stem
but those plants who didn't have green stem or stomata on their stem exchange gases through lenticles
lenticles are present in each plant who did'nt have stomata for gaseous exchange

Gaseous waste in plants is removed through Lenticels.

Lenticels are small openings or pores found in the bark of woody stems and roots of plants. They allow for the exchange of gases, such as oxygen and carbon dioxide, between the internal tissues of the plant and the external environment.

Explanation:

Lenticels serve as a pathway for gaseous exchange in plants. They are present in the periderm, which is the outer protective layer of the stem and roots. The periderm is composed of cork cells, which are dead cells that form a protective covering for the plant.

Gaseous waste produced by the metabolic activities of plant cells, such as carbon dioxide, needs to be eliminated from the plant. At the same time, oxygen from the external environment needs to enter the plant for respiration. Lenticels provide a way for this gaseous exchange to occur.

Key Points:

- Lenticels are small openings or pores found in the bark of woody stems and roots of plants.
- They allow for the exchange of gases between the internal tissues of the plant and the external environment.
- Gaseous waste produced by plant cells, such as carbon dioxide, needs to be eliminated from the plant.
- Oxygen from the external environment needs to enter the plant for respiration.
- Lenticels provide a pathway for gaseous exchange in plants.
- They are present in the periderm, which is the outer protective layer of the stem and roots.
- The periderm is composed of cork cells, which form a protective covering for the plant.

In conclusion, lenticels play a crucial role in the removal of gaseous waste in plants by providing a pathway for the exchange of gases between the internal tissues of the plant and the external environment.
