D. Phellogen, phelloderm and phellem

Answer

To answer the question regarding the other names of secondary cortex, cork cambium, and cork, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structures**: We need to identify the three structures mentioned in the question: secondary cortex, cork cambium, and cork.

2. **Other Names of Each Structure**:
- **Secondary Cortex**: This is also referred to as **Phalloderm**. It is the inner layer that is produced by the cork cambium and consists of parenchyma-like cells.
- **Cork Cambium**: This is known as **Phallogen**. It is the middle layer that produces cork on the outside and phalloderm on the inside.
- **Cork**: This is referred to as **Phylum**. It is the outermost layer that consists of non-living, suberized cells that provide protection.

3. **Summarize the Names**:
- Secondary Cortex = **Phalloderm**
- Cork Cambium = **Phallogen**
- Cork = **Phylum**

4. **Conclusion**: The other names for secondary cortex, cork cambium, and cork are Phalloderm, Phallogen, and Phylum, respectively.

### Final Answer:
- Secondary Cortex: **Phalloderm**
- Cork Cambium: **Phallogen**
- Cork: **Phylum**
