A lenticel has loosely arranged parenchymatous cells on the outer side. These cells, cut off by phellogen are called

Options

A. Complimentary cells
B. Epithem
C. Aerenchyma
D. Sclerenchyma

Answer

To answer the question about the cells that are cut off by phellogen in a lenticel, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Lenticels**: Lenticels are small openings in the bark of woody plants that facilitate gas exchange. They are composed of loosely arranged parenchymatous cells.

2. **Identifying Phellogen**: Phellogen, also known as cork cambium, is a layer of meristematic tissue that gives rise to the cork (phellem) on the outside and the phelloderm on the inside.

3. **Cells Cut Off by Phellogen**: The cells that are produced by the phellogen towards the outside are known as phellem (cork cells), while the cells produced towards the inside are known as phelloderm.

4. **Specific Cells in Lenticels**: In the context of lenticels, the loosely arranged parenchymatous cells on the outer side, which are cut off by the phellogen, are referred to as "complementary cells" or "filling cells".

5. **Conclusion**: Therefore, the cells that are cut off by phellogen in a lenticel are called "complementary cells" or "filling cells".

### Final Answer:
The cells cut off by phellogen in a lenticel are called **complementary cells** or **filling cells**.
