First vascular plant group is

Options

A. Thallophyta
B. Bryophyta
C. Pteridophyta
D. Spermatophyta

Answer

**Step-by-Step Solution:**

1. **Understanding Vascular Plants**: Vascular plants are defined as plants that possess a specialized conducting system for the transport of water, minerals, and food. This system is crucial for their growth and survival.

2. **Components of the Vascular System**: The vascular system consists of two main types of tissues:
- **Xylem**: Responsible for the transport of water and minerals from the roots to the rest of the plant.
- **Phloem**: Responsible for the transport of food (sugars) produced during photosynthesis from the leaves to other parts of the plant.

3. **Types of Vascular Plants**: Vascular plants can be divided into two main categories:
- **Seed Plants**: These include Angiosperms (flowering plants) and Gymnosperms (non-flowering seed plants).
- **Non-Seed Plants**: These include plants that reproduce using spores, such as ferns.

4. **Identifying the First Vascular Plant Group**: Among the non-seed vascular plants, the group known as Pteridophytes is recognized as the first vascular plant group. They are also referred to as:
- **First Vascular Cryptogams**: This term highlights their spore-bearing nature.
- **Spore-Bearing Vascular Plants**: This emphasizes their reproductive method.

5. **Conclusion**: Based on the information provided, the answer to the question "First vascular plant group is" is **Pteridophyte**.

**Final Answer**: Pteridophyte
