Potato and sweet potato have edible parts that are

Options

A. Homologous
B. Analogous
C. Recent introductions
D. Two species of the same genus

Answer

To answer the question regarding the edible parts of potato and sweet potato, we need to analyze their characteristics and the concepts of homologous and analogous structures.

### Step-by-Step Solution:

1. **Identify the Edible Parts**:
- The edible part of the potato is a modified stem known as a tuber.
- The edible part of the sweet potato is a modified root.

2. **Understand the Function**:
- Both the potato and sweet potato serve the same function of storing food. This is a key point in understanding their relationship.

3. **Analyze the Structure**:
- The structure of the potato (a stem) is different from that of the sweet potato (a root). This difference in structure is crucial for classification.

4. **Determine the Relationship**:
- Since the structures are different (stem vs. root) but the function (food storage) is the same, we classify these as analogous organs.

5. **Review Other Options**:
- **Homologous Structures**: These are structures that are similar in form but have different functions (e.g., the forelimbs of mammals).
- **Recent Introductions**: This option does not apply as both plants have been cultivated for a long time.
- **Two Species of the Same Genus**: This is incorrect as potato (Solanum tuberosum) and sweet potato (Ipomoea batatas) belong to different genera.

6. **Conclusion**:
- Therefore, the correct answer is that the edible parts of potato and sweet potato are analogous.

### Final Answer:
The edible parts of potato and sweet potato are **analogous**.
