Moss : Capsule : : Fern …………

Answer

To solve the analogy "Moss : Capsule : : Fern …………", we need to identify the relationship between the terms.

1. **Identify the relationship in the first pair (Moss : Capsule)**:
- Moss is a type of bryophyte, and a capsule is a reproductive structure found in mosses. The capsule is where spores are produced.

2. **Determine the equivalent structure in ferns**:
- Ferns belong to the group known as pteridophytes. In ferns, the equivalent structure that serves a similar function to the capsule in mosses is the sporangium.

3. **Define the function of the sporangium**:
- Just like the capsule in mosses is the center of spore formation, the sporangium in ferns is also responsible for producing spores.

4. **Complete the analogy**:
- Therefore, the complete analogy is "Moss : Capsule : : Fern : Sporangium".

### Final Answer:
Moss : Capsule : : Fern : Sporangium
