Predominant and largest gaemtophyte is of

Options

A. Selaginella
B. Pinus
C. Moss
D. Rice

Answer

To determine the predominant and largest gametophyte among the given options, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Groups**:
- The options provided are Selaginella, Mosses, Pteridophytes (ferns), and Rice.
- Classify these into their respective plant groups:
- Selaginella belongs to Pteridophytes.
- Mosses belong to Bryophytes.
- Rice belongs to Angiosperms.
- The term "Pteridophytes" refers to ferns, which also belong to the vascular plants group.

2. **Understand Gametophyte Dominance**:
- In the plant life cycle, there are two main stages: the sporophyte and the gametophyte.
- Bryophytes (like mosses) have a dominant gametophyte stage, meaning the gametophyte is the main form of the plant that is visible and functional.
- In contrast, in Pteridophytes and Angiosperms, the sporophyte stage is dominant.

3. **Analyze Each Option**:
- **Mosses**: The gametophyte is the predominant stage and is usually the largest part of the plant.
- **Selaginella**: This is a sporophyte-dominant plant; the gametophyte is reduced and not the main form.
- **Pteridophytes (Ferns)**: Similar to Selaginella, ferns have a dominant sporophyte stage.
- **Rice**: As an angiosperm, rice also has a dominant sporophyte stage.

4. **Conclusion**:
- Based on the analysis, the predominant and largest gametophyte is found in **Mosses**.

### Final Answer:
The predominant and largest gametophyte is of **Mosses**.
