Pteridophytes are also called

Options

A. Vascular amphibians of plant kingdom
B. First tracheophytes
C. Botanical snakes
D. All of these

Answer

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

1. **Understanding Pteridophytes**: Pteridophytes are a group of vascular plants that reproduce via spores and do not produce seeds. They include ferns, horsetails, and clubmosses.

2. **Classification**: Pteridophytes are often referred to as the "reptiles of the plant kingdom." This classification is due to their ability to thrive on land while still requiring water for reproduction, similar to how reptiles are primarily terrestrial but have aquatic stages in their life cycles.

3. **Vascular Tissue**: Pteridophytes are characterized by the presence of vascular tissues (xylem and phloem), which allow them to transport water and nutrients efficiently. This is why they are also referred to as "vascular amphibians" of the plant kingdom, as they represent a transition from non-vascular plants (like bryophytes) to fully vascular plants (like angiosperms).

4. **Tracheophytes**: Pteridophytes are considered the first tracheophytes, meaning they are among the first plants to develop specialized tissues for water conduction (tracheids).

5. **Conclusion**: Therefore, pteridophytes can be referred to by multiple names, including "vascular amphibians," "first tracheophytes," and "botanical snakes," as all these terms highlight different aspects of their biology and classification.

**Final Answer**: Pteridophytes are also called "vascular amphibians" of the plant kingdom.
