Gaseous exchange in woody plants occurs through

Options

A. Stomata , Hydathodes
B. Hydathodes , Cuticle
C. Lenticels , Stomata
D. Cuticle

Answer

**Step-by-Step Solution:**

1. **Understanding Gaseous Exchange in Plants:**
Gaseous exchange is a vital process in plants, allowing them to take in carbon dioxide (CO2) for photosynthesis and release oxygen (O2) as a byproduct.

2. **Importance of CO2:**
Carbon dioxide is essential for the process of photosynthesis, which is how plants produce their food. Without CO2, photosynthesis cannot occur effectively.

3. **Role of Stomata:**
Stomata are small openings found primarily on the leaves, but also on stems and other plant organs. They facilitate the exchange of gases (CO2 and O2) between the plant and the atmosphere.

4. **Secondary Growth and Lenticles:**
In woody plants, after secondary growth occurs, lenticels develop on the stems. Lenticels are small pores that also aid in gaseous exchange, especially in areas where stomata are not present.

5. **Conclusion:**
Both stomata and lenticels are crucial for gaseous exchange in woody plants. Stomata are present from the early stages of plant growth, while lenticels appear after secondary growth. Therefore, the correct answer to the question is that gaseous exchange in woody plants occurs through stomata and lenticels.

**Final Answer:**
Gaseous exchange in woody plants occurs through stomata and lenticels.
