C. cuticle
D. sapwood

Answer

To solve the question, "When we peel the skin of a potato tuber, we remove," we can break down the answer step by step.

### Step-by-Step Solution:

1. **Understanding the Structure of Potato Tubers:**
- Potato tubers have several layers, including the outermost layer known as the skin. This skin consists of different tissues.

2. **Identifying the Layers:**
- The outer layer of the potato tuber is primarily made up of the epidermis. However, during the development of the potato tuber, the epidermis is replaced by a different layer.

3. **Defining Periderm:**
- The periderm is a secondary tissue layer that replaces the epidermis as the potato tuber develops. It serves as a protective layer for the tuber.

4. **Understanding the Role of Epidermis:**
- The epidermis is the original outer layer of the potato tuber. However, during the early stages of tuber development, it gets damaged and is replaced by the periderm.

5. **Considering Other Options:**
- The cuticle is a waxy layer that helps prevent water loss but is not the primary layer we remove when peeling a potato.
- Saponin is a compound found in potatoes but is not a structural layer of the skin.

6. **Conclusion:**
- When we peel the skin of a potato tuber, we are primarily removing the periderm, which has replaced the epidermis during the tuber’s development.

Thus, the correct answer is that when we peel the skin of a potato tuber, we remove **periderm**.
