Lenticels are involved in

Options

A. Food transport
B. Photosynthesis
C. Transpiration
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Lenticels**: Lenticels are small, lens-like pores found on the surface of woody stems and branches of trees. They are important structures that facilitate gas exchange.

2. **Functions of Lenticels**: The primary functions of lenticels include:
- **Gaseous Exchange**: Lenticels allow for the exchange of gases (such as oxygen and carbon dioxide) between the internal tissues of the plant and the external environment.
- **Transpiration**: Lenticels also play a minor role in transpiration, which is the process of water vapor loss from the plant. However, this contribution is minimal, accounting for only about 0.1% of the total transpiration in plants.

3. **Eliminating Incorrect Options**:
- **Food Transport**: Lenticels are not involved in the transport of food within the plant.
- **Photosynthesis**: Lenticels do not participate in the process of photosynthesis, which occurs primarily in the leaves.
- **None of the Above**: This option is incorrect since lenticels do have a function, specifically in transpiration and gas exchange.

4. **Conclusion**: Based on the functions of lenticels, the correct answer to the question is that they are involved in **transpiration**.

**Final Answer**: The correct option is **transpiration**.
