Bryophytes absorb most of their water through.

Options

A. Rhizoids
B. Roots
C. Mycorrhizae
D. Above-ground structures.

Answer

### Step-by-Step Solution:

1. **Understanding Bryophytes**:
- Bryophytes are non-vascular plants, which means they lack specialized tissues for transporting water and nutrients. They include mosses, liverworts, and hornworts.

2. **Structure of Bryophytes**:
- The body of bryophytes is predominantly haploid, and they do not have well-differentiated leaves and stems like higher plants.

3. **Water Absorption in Bryophytes**:
- Bryophytes typically live in moist environments because they require water for fertilization.

4. **Role of Rhizoids**:
- Bryophytes have structures called rhizoids, which are root-like and can absorb some water. However, their primary function is to anchor the plant rather than to absorb significant amounts of water.

5. **Above Ground Structures**:
- The main structures responsible for water absorption in bryophytes are the leaves. Although the leaves are not well differentiated, they are the primary sites for water absorption due to their exposure to moisture in the environment.

6. **Conclusion**:
- Most of the water in bryophytes is absorbed through their leaves, which are adapted to take in moisture from the surrounding environment.

### Final Answer:
Bryophytes absorb most of their water through their leaves.
