Tracheids differ from other tracheary elements in

Options

A. Lacking nucleus
B. Being lignified
C. Having casparian strips
D. Being imperforate

Explanation

To answer the question "Tracheids differ from other tracheary elements in which way?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Tracheary Elements**:
- Tracheary elements are specialized cells in the xylem responsible for the conduction of water and minerals. They include tracheids and vessels.

2. **Identifying Types of Tracheary Elements**:
- There are two main types of tracheary elements:
- **Tracheids**: Long, narrow cells with tapered ends.
- **Vessels**: Shorter, wider cells that are connected end-to-end to form long tubes.

3. **Analyzing the Options**:
- The question provides several options to differentiate tracheids from other tracheary elements.
- We need to evaluate each option based on the characteristics of tracheids and vessels.

4. **Evaluating Option 1 - Lack of Nucleus**:
- Both tracheids and vessels lose their nuclei at maturity, so this option is incorrect.

5. **Evaluating Option 2 - Lignification**:
- Both tracheids and vessels are lignified, meaning they have a tough, woody structure. This option is also incorrect.

6. **Evaluating Option 3 - Presence of Casparian Strips**:
- Casparian strips are found in the endodermis of roots, not specifically in tracheids or vessels. Therefore, this option is incorrect.

7. **Evaluating Option 4 - Presence of Bordered Pits**:
- Tracheids have bordered pits that allow for the lateral movement of water between adjacent tracheids. In contrast, vessels have perforation plates that allow for efficient water flow between vessel elements. This option is correct.

8. **Conclusion**:
- The primary difference between tracheids and other tracheary elements (like vessels) is that tracheids possess bordered pits, while vessels have perforation plates.

### Final Answer:
Tracheids differ from other tracheary elements in that they have bordered pits, which facilitate lateral water movement.
