In hepaticae/liverworts of bryophytes, the majority is

Options

A. Flattened thalloids
B. Foliose
C. Discoid
D. Rosette.

Answer

**Step-by-Step Solution:**

1. **Understanding Hepaticae/Liverworts**: Hepaticae, commonly known as liverworts, are a group of non-vascular plants classified under the division Bryophyta. They are characterized by their simple structure and lack of true roots, stems, and leaves.

2. **Structure of Liverworts**: Liverworts have a thallus (the main body) that is typically flat and lobed. The thallus is not well-developed compared to other plant structures. It often grows in a plaque-like form and is attached to the ground.

3. **Types of Thallus**: In liverworts, the thallus can be categorized into two types:
- **Thallose liverworts**: These have a flattened, lobed structure.
- **Leafy liverworts**: These have structures that resemble leaves.

4. **Majority Structure**: The majority of liverworts exhibit the thallose form, which is characterized by a flat and lobed appearance. This structure allows them to efficiently absorb water and nutrients from their surroundings.

5. **Conclusion**: Therefore, the majority of liverworts (hepaticae) are thallose in structure, which is a key characteristic of this group of bryophytes.

**Final Answer**: The majority of liverworts (hepaticae) are thallose in structure.
