The gaseous wastes of respiration and photosynthesis in plants are removed through stomata and lenticels.Lenticels are a body of cells on the stem which acts as a pore and enables the transfer of gaseous wastes into the atmosphere while Stoma is a pore found in the epidermis of leaves and stems and controls the gaseous exachange in plants. The exchange of gases through these pores is by simple diffusion.

**Gaseous Wastes in Respiration and Photosynthesis in Plants**

Plants have a unique way of getting rid of their gaseous wastes, which are produced during respiration and photosynthesis. These gaseous wastes include carbon dioxide (CO2) and oxygen (O2). The removal of these wastes is essential for the proper functioning and survival of the plant.

**Stomata of Leaves:**

Stomata are small openings present on the surface of leaves and stems of plants. They are surrounded by specialized cells called guard cells, which control their opening and closing. Stomata serve as the primary site for gas exchange in plants. During photosynthesis, plants take in carbon dioxide through the stomata, which is necessary for the process. Similarly, during respiration, plants release oxygen as a waste product through these openings.

**Lenticels of Stem:**

Lenticels are small, corky pores or openings present on the surface of stems and other woody parts of plants. They allow for the exchange of gases between the internal tissues of the plant and the external environment. While stomata are mainly responsible for gas exchange in leaves, lenticels play a similar role in stems. They allow the exchange of gases, including the removal of gaseous wastes such as carbon dioxide and oxygen.

**Stomata and Lenticels:**

Both stomata and lenticels are involved in the removal of gaseous wastes in plants. Stomata are primarily responsible for gas exchange in leaves, while lenticels fulfill this function in stems and other woody parts of the plant. Through these openings, plants release oxygen produced during photosynthesis and eliminate carbon dioxide generated during respiration.

**Conclusion:**

In conclusion, the gaseous wastes of respiration and photosynthesis in plants are removed through stomata of leaves and lenticels of stems. These openings allow for the exchange of gases between the internal tissues of the plant and the external environment, ensuring the removal of waste gases and the intake of necessary gases. Therefore, option 'C' is the correct answer.
