Dryopteris differs from Funaria in having

Options

A. an independent gametophyte
B. an independent sporophyte
C. swimming antherozoids
D. archegonia

Answer

To answer the question "Dryopteris differs from Funaria in having," we need to understand the key differences between these two types of plants, which belong to different groups in the plant kingdom.

### Step-by-Step Solution:

1. **Identify the Groups**:
- Dryopteris is a pteridophyte, which means it is a type of fern.
- Funaria is a bryophyte, specifically a moss.

2. **Main Plant Body**:
- In Dryopteris (pteridophyte), the main plant body is the diploid sporophyte. This sporophyte is the dominant phase of the life cycle and is independent.
- In Funaria (bryophyte), the main plant body is the haploid gametophyte, which is also independent and photosynthetic. The sporophyte in Funaria is short-lived and dependent on the gametophyte.

3. **Alternation of Generations**:
- Dryopteris exhibits a life cycle where the diploid sporophyte alternates with a multicellular and independent haploid gametophyte.
- Funaria alternates with a short-lived sporophyte that is dependent on the gametophyte.

4. **Independent Structures**:
- The key distinction here is that in Dryopteris, the sporophyte is independent and photosynthetic, while in Funaria, the sporophyte is dependent on the gametophyte for nutrition and support.

5. **Conclusion**:
- Therefore, the correct answer to the question is that Dryopteris differs from Funaria in having an **independent sporophyte**.

### Final Answer:
Dryopteris differs from Funaria in having an **independent sporophyte**.
