First amphibian plants of the plant kingdom are

Options

A. Thallophytes
B. Bryophytes
C. pteridophytes
D. Gymnosperms

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:** The question asks for the first amphibian plants of the plant kingdom. To answer this, we need to identify which group of plants can thrive in both aquatic and terrestrial environments.

2. **Analyzing the Options:**
- **Thallophytes:** These are primarily aquatic plants, such as algae, and do not live on land. Therefore, they cannot be classified as amphibian plants.
- **Bryophytes:** These plants, including mosses and liverworts, can live in both water and on land. They are non-vascular and require water for reproduction, particularly for the movement of male gametes to female gametes.
- **Pteridophytes:** These are vascular plants (like ferns) that can also be found in both habitats but are considered secondary amphibians, as they evolved after bryophytes.
- **Gymnosperms:** These are primarily terrestrial plants and do not thrive in aquatic environments.

3. **Identifying the Correct Answer:** Since bryophytes are the first group of plants that can survive in both water and land, they are classified as the first amphibian plants of the plant kingdom.

4. **Conclusion:** The correct answer is **Bryophytes** (Option B).
