In Mosses creeping, green, branched and frequently filamentous stage is called"-

Options

A. Protonema
B. Rhizome
C. Rhizophore
D. All of these

Answer

### Step-by-Step Solution:

1. **Understanding Mosses**: Mosses are a type of bryophyte, which are non-vascular plants. They typically have a life cycle that includes both a gametophyte and a sporophyte stage.

2. **Identifying the Stage**: The question asks about the creeping, green, branched, and frequently filamentous stage in mosses.

3. **Recognizing Key Terms**: The term "protonema" refers to the initial stage of the moss life cycle, which is a filamentous structure that develops from a germinating spore.

4. **Explaining Protonema**: When a moss spore germinates, it forms a protonema, which resembles a green mat or filament. This structure is crucial for the development of the mature gametophyte.

5. **Evaluating Options**:
- **Protonema**: This is the correct answer as it describes the filamentous stage in mosses.
- **Rhizome**: This is a type of underground stem, not specific to mosses.
- **Rhizophore**: This is a structure found in some plants that helps anchor them, but it is not related to the moss life cycle.
- **All of the above**: Since only protonema is correct, this option is not valid.

6. **Conclusion**: The correct answer to the question is "Protonema," which is the creeping, green, branched, and frequently filamentous stage in mosses.

### Final Answer:
The creeping, green, branched, and frequently filamentous stage in mosses is called **Protonema**.
