Options

A. Phellem
B. Wood
C. Periderm
D. Phelloderm

Answer

To answer the question "The photosynthetic part of periderm that lies inner to phellogen is", we need to understand the structure of periderm and its components. Here’s a step-by-step solution:

### Step 1: Understand the Components of Periderm
The periderm consists of three main layers:
1. **Phellium (Cork)**: This is the outermost layer of the periderm.
2. **Phellogen (Cork Cambium)**: This is the middle layer that is responsible for producing new cork cells.
3. **Phelloderm (Secondary Cortex)**: This is the innermost layer that lies beneath the phellogen.

### Step 2: Identify the Photosynthetic Part
Among these layers, the phelloderm is known to have photosynthetic capabilities. It is the layer that is located inner to the phellogen.

### Step 3: Conclusion
Since the question specifically asks for the photosynthetic part of the periderm that lies inner to the phellogen, the correct answer is **Phelloderm**.

### Final Answer
The photosynthetic part of periderm that lies inner to phellogen is **Phelloderm**.
