First well developed terrestrial plant is

Options

A. Bryophytes
B. Pteridophytes
C. Algae
D. Gymnosperms

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks for the first well-developed terrestrial plant. This implies we are looking for a plant that is adapted to live on land and has developed structures to support its growth and reproduction.

2. **Identifying Plant Categories**: Plants are classified into various categories. In this context, we focus on cryptogams, which include algae, bryophytes, and pteridophytes.

3. **Analyzing Plant Types**:
- **Algae**: These are primarily aquatic and do not have vascular tissues.
- **Bryophytes**: These include mosses and liverworts, which are also non-vascular and typically found in moist environments.
- **Pteridophytes**: This group includes ferns and is characterized by the presence of vascular tissues (xylem and phloem).

4. **Vascular Tissues**: Vascular tissues are crucial for the transport of water, nutrients, and food within the plant. Xylem is responsible for transporting water and nutrients, while phloem transports food.

5. **Conclusion**: Among the mentioned groups, pteridophytes are the first well-developed terrestrial plants because they possess vascular tissues, allowing them to thrive on land.

6. **Final Answer**: The first well-developed terrestrial plant is **Pteridophytes**.
