B. (b) Seed
C. (c) Archegonia
D. (d) Embryo

Answer

To solve the question regarding the differences between Funaria and Pteridium, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organisms**:
- Funaria is a genus of mosses, classified as a bryophyte.
- Pteridium is a genus of ferns, classified as a pteridophyte.

2. **Understand the Classification**:
- Bryophytes (like Funaria) are simple, non-vascular plants that do not have true roots, stems, or leaves.
- Pteridophytes (like Pteridium) are more advanced vascular plants that have a well-defined structure including roots, stems, and leaves.

3. **Analyze the Options**:
- **Option A: Roots**: Roots are present in Pteridium but absent in Funaria.
- **Option B: Seeds**: Neither Funaria nor Pteridium produces seeds, as both are non-seed producing plants.
- **Option C: Archegonia**: Archegonia, which are female reproductive structures, are present in both Funaria and Pteridium.
- **Option D: Embryo**: Embryos are also present in both Funaria and Pteridium.

4. **Determine the Correct Answer**:
- Since Funaria lacks roots, which are present in Pteridium, the correct answer to the question is that Funaria differs from Pteridium in the absence of roots.

### Final Answer:
Funaria differs from Pteridium in the absence of **roots**.
