Dominant gametophytic generation is found in `:`

Options

A. Pteriodophyte
B. Angiosperm monocots
C. Gymnosperm
D. Bryophytes

Answer

To determine which group of plants has a dominant gametophytic generation, we can analyze the characteristics of different plant groups step by step.

### Step-by-Step Solution:

1. **Identify Plant Groups**: We start by listing the main groups of plants: ferns, horsetails, angiosperms, gymnosperms, and bryophytes.

2. **Examine Ferns and Horsetails**:
- Ferns and horsetails are part of the pteridophytes.
- In these plants, the dominant generation is the sporophyte, not the gametophyte.
- Therefore, this option is incorrect.

3. **Examine Angiosperms**:
- Angiosperms are flowering plants that produce seeds enclosed within an ovary.
- In angiosperms, the dominant generation is also the sporophyte.
- Thus, this option is also incorrect.

4. **Examine Gymnosperms**:
- Gymnosperms are seed-producing plants with naked seeds.
- Similar to angiosperms, gymnosperms have a dominant sporophytic generation.
- Hence, this option is incorrect as well.

5. **Examine Bryophytes**:
- Bryophytes include mosses and liverworts.
- They are known as the amphibians of the plant kingdom because they require water for reproduction.
- In bryophytes, the dominant generation is the gametophyte, which is independent and photosynthetic, while the sporophyte is dependent on the gametophyte for nutrition.
- Therefore, this option is correct.

### Conclusion:
The dominant gametophytic generation is found in **Bryophytes**.
