Sporogonium of Riccia is made of

Options

A. Foot and capsule
B. Foot, seta and capsule
C. Capsule only
D. Seta and capsule.

Answer

To determine what the sporogonium of Riccia is made of, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Sporogonium**: The sporogonium is the sporophyte generation in bryophytes, including Riccia. It is responsible for producing spores.

2. **Identifying Components**: The sporogonium can have various structures, but we need to identify which components are present in Riccia specifically.

3. **Analyzing the Options**: The options provided are:
- A) Foot and capsule
- B) Foot, seta, and capsule
- C) Capsule only
- D) Seta and capsule

4. **Evaluating Each Option**:
- **Option A (Foot and capsule)**: This suggests the presence of a foot structure, which is not characteristic of Riccia's sporogonium.
- **Option B (Foot, seta, and capsule)**: This indicates a more complex structure, which is not applicable to Riccia as it has a simpler sporophyte.
- **Option C (Capsule only)**: This option states that the sporogonium consists solely of a capsule, which aligns with the known structure of Riccia.
- **Option D (Seta and capsule)**: Similar to option B, this implies additional structures that are not present in Riccia.

5. **Conclusion**: Based on the analysis, the sporogonium of Riccia is made up of a capsule only.

### Final Answer:
The sporogonium of Riccia is made of **capsule only** (Option C).
