the cells forming phellogen are.

Options

A. collenchymatous
B. paraenchymatous
C. parencymatous or collenchymatus
D. Recently divided cortical cells.

Answer

To answer the question about the cells forming phellogen, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Phellogen**:
- Phellogen, also known as cork cambium, is a type of lateral meristem in plants. It is responsible for the production of cork cells (phellem) and contributes to the secondary growth of the plant.

2. **Types of Cells Involved**:
- The cells that form phellogen are primarily parenchymatous cells. These cells are living, thin-walled, and capable of division.

3. **Role of Phellogen**:
- Phellogen contributes to the formation of periderm, which replaces the epidermis in plants undergoing secondary growth. The periderm consists of phellem (cork), phellogen (cork cambium), and phelloderm.

4. **Conclusion**:
- Therefore, the cells forming phellogen are parenchymatous cells.

### Final Answer:
The cells forming phellogen are parenchymatous cells.
