The chief water conducting elements of xylem in gymnosperms are

Options

A. Tracheids
B. Vessels
C. Fibers
D. Transfusion tissue

Answer

**Step-by-Step Solution:**

1. **Understanding Xylem Function**: Xylem is responsible for the conduction of water and minerals from the roots to the rest of the plant. It consists of various types of cells that facilitate this process.

2. **Identifying Xylem Components**: The main components of xylem include tracheids, vessels, fibers, and transfusion tissue. Each of these has different roles and efficiencies in water conduction.

3. **Focusing on Gymnosperms**: Gymnosperms are a group of plants that do not produce flowers or fruits. They primarily use tracheids for water conduction.

4. **Analyzing the Options**:
- **Tracheids**: These are elongated cells that are tapered at the ends and have pits for water movement. They are the primary water-conducting elements in gymnosperms.
- **Vessels**: These are more efficient water-conducting structures found mainly in angiosperms (flowering plants).
- **Fibers**: These provide structural support but do not conduct water.
- **Transfusion Tissue**: This is a specialized tissue found in some plants but is not the main conducting element in gymnosperms.

5. **Conclusion**: Since tracheids are the primary water-conducting elements in gymnosperms, the correct answer to the question is **tracheids**.

**Final Answer**: The chief water conducting elements of xylem in gymnosperms are **tracheids**.
