Lenticles are formed by rupturing of the epidermis by

Options

A. Collenchyma cells
B. Parenchyma cells
C. Sclerenchyma cells
D. Vascular cambium

Answer

### Step-by-Step Solution:

1. **Understanding Lenticels**:
- Lenticels are small pores found on the stems of plants. They play a crucial role in gas exchange, allowing oxygen and carbon dioxide to enter and exit the plant.

2. **Formation of Lenticels**:
- Lenticels are formed when the epidermis of the plant ruptures. This rupture is essential for the formation of these structures.

3. **Identifying the Tissue Involved**:
- After the epidermis ruptures, the underlying tissue that is affected is important to identify. The options provided include:
- **Cholenchyma**: A type of tissue that provides support and is characterized by its chlorophyll content. However, it is located deeper in the plant and does not contribute to the formation of lenticels.
- **Parenchyma**: This is a type of permanent tissue that is involved in various functions, including storage and gas exchange. It is located just beneath the epidermis and is the primary tissue that is ruptured to form lenticels.
- **Sclerenchyma**: This tissue provides structural support and is not involved in the formation of lenticels.
- **Vascular Cambium**: This is a layer of tissue responsible for secondary growth in plants and is located beneath the xylem and phloem, thus not involved in the formation of lenticels.

4. **Conclusion**:
- Based on the analysis, the tissue that is ruptured after the epidermis to form lenticels is **parenchyma cells**. This rupture allows for the necessary gas exchange to occur.

### Final Answer:
Lenticels are formed by the rupturing of the epidermis by **parenchyma cells**.
