Seed habit originated in certain

Options

A. Bryophytes
B. Ferns
C. Angiosperms
D. Gymnosperm

Answer

To solve the question "Seed habit originated in certain," we need to analyze the options provided and understand the characteristics of each group of plants mentioned.

### Step-by-Step Solution:

1. **Understanding Seed Habit**:
- The term "seed habit" refers to the development of seeds, which are crucial for the reproduction and survival of many plant species. Seeds can be either naked (not enclosed) or enclosed in a fruit.

2. **Analyzing the Options**:
- **Option A: Bryophytes**: These are non-vascular plants (like mosses) that do not produce seeds. Instead, they reproduce using spores.
- **Option B: Ferns**: Ferns are vascular plants that also reproduce via spores. However, they are considered to be more advanced than bryophytes and show some characteristics that are precursors to seed development.
- **Option C: Angiosperms**: These are flowering plants that produce seeds enclosed within fruits. They are the most advanced group in terms of seed development.
- **Option D: Gymnosperms**: These are plants that produce naked seeds, such as conifers. They are more advanced than ferns but less so than angiosperms.

3. **Identifying the Origin of Seed Habit**:
- The seed habit is believed to have originated in the group of plants that show the transition from spore-based reproduction to seed-based reproduction. This transition is most evident in the ferns, which represent a significant evolutionary step towards seed development.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Option B: Ferns**. While angiosperms and gymnosperms are more advanced in seed development, the initial origin of the seed habit can be traced back to ferns.

### Final Answer:
**Option B: Ferns**
