The only group of seedless tracheophytes is

Options

A. Bryophyta
B. Gymnosperm
C. Pteridophytes
D. Algae

Answer

**Step-by-Step Solution:**

1. **Understanding Tracheophytes**:
- Tracheophytes are vascular plants that have specialized tissues (xylem and phloem) for the transport of water, nutrients, and food.

2. **Identifying Seedless Tracheophytes**:
- Among tracheophytes, there exists a group known as seedless tracheophytes. This group does not produce seeds for reproduction.

3. **Recognizing the Group**:
- The only group of seedless tracheophytes is known as "teridophytes." These plants are characterized by their ability to reproduce via spores rather than seeds.

4. **Characteristics of Teridophytes**:
- Teridophytes include ferns and horsetails. They possess vascular tissues and have distinct reproductive structures:
- Male sex organ: Antheridium (produces sperm)
- Female sex organ: Archegonium (produces egg)

5. **Fertilization Process**:
- The sperm produced by the antheridium requires water to swim towards the egg in the archegonium for fertilization. This highlights the dependency on water for reproduction.

6. **Conclusion**:
- Therefore, the answer to the question is that the only group of seedless tracheophytes is "teridophytes."

**Final Answer**: Teridophytes
