Protosteles are found in

Options

A. Bryophyta
B. Gymnosperms
C. Pteridophyta
D. Angiosperms

Answer

**Step-by-Step Solution:**

1. **Understanding Protosteles**:
- Protosteles are a type of vascular tissue arrangement found in some plants. They are characterized by having a solid core of xylem surrounded by phloem.

2. **Identifying Plant Groups**:
- The question provides four options: Bryophytes, Gymnosperms, Pteridophytes, and Angiosperms. We need to determine which of these groups contains protosteles.

3. **Analyzing Each Option**:
- **Bryophytes**: These are non-vascular plants and do not have a complex vascular system like protosteles.
- **Gymnosperms**: These have a more advanced vascular system but do not typically exhibit protostelic arrangements.
- **Pteridophytes**: This group includes ferns and other similar plants that do exhibit protostelic arrangements, particularly in their rhizomes.
- **Angiosperms**: These are flowering plants and generally do not have protosteles.

4. **Conclusion**:
- Based on the analysis, protosteles are primarily found in **Pteridophytes**. Therefore, the correct answer is option three: **Pteridophytes**.
