The predominant stage of the life cycle of a moss is the gametophyte which consists of

Options

A. Two stages
B. Three stages
C. Four stages
D. One stages

Answer

To answer the question regarding the predominant stage of the life cycle of a moss, which is the gametophyte, we can break it down into a step-by-step solution.

### Step-by-Step Solution:

1. **Identify the Predominant Stage**:
- The life cycle of mosses is characterized by two main stages: the gametophyte and the sporophyte. The question specifically asks about the gametophyte stage, which is the dominant and most recognizable phase in mosses.

2. **Understand the Structure of the Gametophyte**:
- The gametophyte stage of moss consists of two distinct phases: the protonema stage and the leafy stage.

3. **Protonema Stage**:
- The first stage is the protonema. This is a filamentous structure that develops directly from a spore. It is green, branched, and often resembles a moss lawn. The protonema is crucial for the establishment of the moss plant.

4. **Leafy Stage**:
- The second stage is the leafy stage, which develops from the protonema. This stage consists of the typical moss plant that we recognize, with leaves arranged spirally around a central stem. The leafy stage arises from lateral buds on the protonema.

5. **Conclusion**:
- Therefore, the gametophyte stage of moss consists of **two stages**: the protonema stage and the leafy stage.

### Final Answer:
The correct answer is that the gametophyte consists of **2 stages**.
