Phellogen cuts -

Options

A. Cork / phellogen inside and secondary cortex (phelloderm) outside
B. Cork outside and phelloderm inside
C. Both cork and phelloderm inside
D. Both cork and phelloderm outside

Answer

### Step-by-Step Solution:

1. **Understanding Phellogen**: Phellogen, also known as cork cambium, is a type of lateral meristematic tissue found in plants. It is responsible for the production of cork (phellem) and pheloderm.

2. **Location of Phellogen**: Phellogen is located in the cortex of the plant. It is formed from the cortical cells, which are the cells located in the outer layers of the stem or root.

3. **Products of Phellogen**: The cork cambium (phellogen) produces two main structures:
- **Cork (Phellem)**: This is produced on the outer side of the phellogen. It serves as a protective layer for the plant.
- **Pheloderm**: This is produced on the inner side of the phellogen. It is a secondary cortex that provides additional support and storage.

4. **Analyzing Options**:
- **Option 1**: Cork on the outside and phellogen inside - Incorrect.
- **Option 2**: Cork on the outside and pheloderm on the inside - Correct.
- **Option 3**: Both cork and pheloderm inside - Incorrect.
- **Option 4**: Both cork and pheloderm outside - Incorrect.

5. **Conclusion**: Based on the functions and location of phellogen, the correct answer is **Option 2**, which states that cork is on the outside and pheloderm is on the inside.
