Pteridophytes differ from bryophytes in possessing:

Options

A. spores
B. archegonia
C. vascular tissue
D. alternation of generation

Answer

**Step-by-Step Solution:**

1. **Understanding the Groups**:
- Pteridophytes and bryophytes are two major groups of plants. Pteridophytes include ferns and their relatives, while bryophytes include mosses and liverworts.

2. **Key Characteristics of Bryophytes**:
- Bryophytes are non-vascular plants, meaning they do not have specialized tissues for transporting water and nutrients. They typically grow in moist environments and are less complex in structure.

3. **Key Characteristics of Pteridophytes**:
- Pteridophytes are vascular plants, which means they possess specialized tissues called xylem and phloem. These tissues allow for the efficient transport of water, nutrients, and food throughout the plant.

4. **Comparison of Vascular Tissue**:
- The presence of vascular tissue is a significant difference between pteridophytes and bryophytes. Pteridophytes have well-developed vascular systems, while bryophytes lack these structures.

5. **Conclusion**:
- Therefore, the primary way in which pteridophytes differ from bryophytes is in their possession of vascular tissue, which includes xylem and phloem.

**Final Answer**: Pteridophytes differ from bryophytes in possessing vascular tissue.
