Gametophyte is dominant, photosynthetic, sexually reproducing and independent in

Options

A. Angiosperms
B. Gymnosperms
C. Bryophyta
D. pteridophyta.

Answer

To solve the question regarding which group of plants has a dominant, photosynthetic, sexually reproducing, and independent gametophyte, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Gametophyte**: The haploid stage in the life cycle of plants that produces gametes (sperm and eggs).
- **Dominant**: The stage that is more prominent or larger in size compared to the other stage (sporophyte).
- **Photosynthetic**: Capable of photosynthesis, meaning it can produce its own food using sunlight.
- **Sexually Reproducing**: Involves the fusion of gametes to form a zygote.
- **Independent**: Not reliant on another structure for survival.

2. **Identify the Groups**:
- **Angiosperms**: Flowering plants where the sporophyte is the dominant stage.
- **Gymnosperms**: Non-flowering plants like conifers; also have a dominant sporophyte stage.
- **Bryophyta**: Includes mosses and liverworts, where the gametophyte is the dominant stage.
- **Pteridophyta**: Ferns and their relatives, where the sporophyte is the dominant stage.

3. **Analyze Bryophyta**:
- In Bryophyta, the gametophyte is the main plant body. It is photosynthetic, independent, and reproduces sexually by producing gametes.
- The sporophyte is typically dependent on the gametophyte for nutrition and is not photosynthetic in its early stages.

4. **Conclusion**:
- Based on the characteristics of the gametophyte in the different plant groups, the correct answer is **C. Bryophyta**.

### Final Answer:
The gametophyte is dominant, photosynthetic, sexually reproducing, and independent in **C. Bryophyta**.
