B. Bark
C. Periderm
D. Lenticel

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about a specific type of opening found in the woody stem of plants, characterized as lens-shaped.

2. **Identifying the Options:**
The options provided are:
- A) Stomata
- B) Bark
- C) Periderm
- D) Lenticel

3. **Analyzing Each Option:**
- **Stomata:** These are small openings primarily found on the leaves and are involved in gas exchange (oxygen and carbon dioxide). They are not lens-shaped and are not located in the woody stem.
- **Bark:** This is the outer protective layer of the woody stem but does not have lens-shaped openings.
- **Periderm:** This is a protective tissue that forms after secondary growth, but it does not refer to lens-shaped openings.
- **Lenticel:** These are indeed lens-shaped openings found in the bark of woody stems. They facilitate gas exchange between the internal tissues of the plant and the atmosphere.

4. **Conclusion:**
Based on the analysis, the correct answer is **D) Lenticel**. Lenticels are the lens-shaped openings in the woody stem that allow for gas exchange.
