Tracheids are found in all the following plants, except

Options

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

Answer

To solve the question "Tracheids are found in all the following plants, except," we need to analyze the presence of tracheids in different plant groups: pteridophytes, gymnosperms, bryophytes, and angiosperms.

### Step-by-Step Solution:

1. **Understanding Tracheids**:
- Tracheids are a type of water-conducting cell found in the xylem of vascular plants. They are responsible for the transport of water and minerals.

2. **Identifying Plant Groups**:
- We need to evaluate the presence of tracheids in the following groups:
- Pteridophytes
- Gymnosperms
- Bryophytes
- Angiosperms

3. **Analyzing Pteridophytes**:
- Pteridophytes are the first vascular plants and contain a well-developed vascular system.
- They have tracheids, but they lack vessels.

4. **Analyzing Gymnosperms**:
- Gymnosperms also have a well-developed vascular system.
- They contain tracheids but do not have vessels.

5. **Analyzing Angiosperms**:
- Angiosperms have a complete vascular system, including both tracheids and vessels.

6. **Analyzing Bryophytes**:
- Bryophytes are non-vascular plants, meaning they do not have a vascular system.
- Consequently, they lack both xylem and phloem, and therefore, tracheids are absent in bryophytes.

7. **Conclusion**:
- Based on the analysis, tracheids are found in pteridophytes, gymnosperms, and angiosperms, but they are absent in bryophytes.
- Thus, the answer to the question is **bryophytes**.

### Final Answer:
Tracheids are found in all the following plants, except **bryophytes**.
