Sporophyte of Riccia contains

Options

A. Spores, elaters and nutritive cells
B. Spores and nutritive cells
C. Elaters and spores
D. Spores only.

Answer

To answer the question "Sporophyte of Riccia contains," we will analyze the structure and components of the sporophyte in Riccia, which is a type of liverwort.

### Step-by-Step Solution:

1. **Understanding Riccia**:
- Riccia is a genus of liverworts, which are non-vascular plants classified under the phylum Bryophyta.
- Bryophytes are characterized by their simple structure and lack of a well-developed vascular system.

2. **Identifying the Sporophyte**:
- The sporophyte is the diploid generation in the life cycle of liverworts. In Riccia, the sporophyte is relatively simple.
- It typically consists of a capsule that is embedded in the gametophyte.

3. **Components of the Sporophyte**:
- The main components of the sporophyte in Riccia include:
- **Spores**: The primary reproductive units that are produced within the capsule.
- **Nutritive Cells (Nurse Cells)**: These are specialized cells that provide nutrition to the developing spores. They are sterile mother cells that do not produce spores but support the growth of the spores.

4. **Excluding Other Options**:
- The options provided included elaters, which are present in some other bryophytes but not in Riccia. Therefore, options that included elaters can be ruled out.
- The correct option must include both spores and nutritive cells.

5. **Conclusion**:
- Based on the analysis, the sporophyte of Riccia contains **spores and nutritive cells**.

### Final Answer:
The sporophyte of Riccia contains **spores and nutritive cells**.
