Which of the following plant kingdom is called 'amphibians' ?

Options

A. Gymnosperm
B. Thallophyta
C. Tracheophyta
D. Bryophyta

Answer

To answer the question "Which of the following plant kingdom is called 'amphibians'?", we will analyze the options provided and understand the characteristics of different plant groups.

### Step-by-Step Solution:

1. **Understanding the Term 'Amphibians':**
- The term 'amphibians' is generally used to describe animals that can live both in water and on land. In the context of plants, we are looking for a group that has similar characteristics.

2. **Analyzing the Options:**
- **Gymnosperms:** These are plants that produce naked seeds and are primarily found on land. They do not have a significant aquatic phase. Therefore, they cannot be classified as 'amphibians'.
- **Thalophyta:** This group includes algae, which are primarily aquatic and do not typically inhabit terrestrial environments. Thus, they do not fit the 'amphibian' classification.
- **Tracheophyta:** This group includes vascular plants such as Pteridophyta (ferns), Gymnosperms, and Angiosperms. While some of these plants may have adaptations for life on land, they do not specifically represent the 'amphibian' characteristic.
- **Bryophyta:** This group includes mosses and liverworts. Bryophytes are known to thrive in both terrestrial and aquatic environments. They are often found in moist areas and can reproduce in water, making them the closest match to the term 'amphibians' in the plant kingdom.

3. **Conclusion:**
- Based on the analysis, the plant kingdom that is referred to as 'amphibians' is **Bryophyta**.

### Final Answer:
**Bryophyta** is called 'amphibians' in the plant kingdom.
