Lenticles are formed by rupturing of the epidermis by

Options

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

Answer

To solve the question regarding the formation of lenticels, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Lenticels**:
- Lenticels are small openings in the bark of woody plants that allow for gas exchange. They are essential for the respiration of the plant.

2. **Identifying the Tissue Involved**:
- The question asks which type of cells are responsible for the rupturing of the epidermis to form lenticels. The options provided are cholenchyma cells, parenchyma cells, sclerenchyma cells, and vascular cambium.

3. **Role of Parenchyma Cells**:
- Parenchyma cells are living cells that are involved in various functions, including storage, photosynthesis, and tissue repair. They can divide and increase in size.

4. **Mechanism of Formation**:
- As parenchyma cells beneath the epidermis divide and grow, they exert pressure on the epidermis. This pressure causes the epidermis to rupture, leading to the formation of lenticels.

5. **Conclusion**:
- Based on the above reasoning, the correct answer is that lenticels are formed by the rupturing of the epidermis by **parenchyma cells**.

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