Major xylary element in wood of a gymnospermic plant is

Options

A. Vessel
B. Tracheid
C. Xylem fibre
D. Xylem parenchyma

Answer

**Step-by-Step Solution:**

1. **Understanding Xylem Components**:
- Xylem is a type of tissue in vascular plants responsible for the conduction of water and minerals. It consists of various types of cells known as xylem elements.

2. **Identifying Xylem Elements**:
- The major xylem elements include:
- **Tracheids**: Long, narrow cells that conduct water and are present in both gymnosperms and angiosperms.
- **Vessels**: Shorter, wider cells that are primarily found in angiosperms and are absent in gymnosperms.
- **Xylem Fibers**: These are supportive cells made of sclerenchyma, which are dead at maturity.
- **Xylem Parenchyma**: Living cells that serve in storage and are involved in the transport of nutrients.

3. **Focusing on Gymnosperms**:
- Gymnosperms are a group of plants that do not have vessels; instead, they primarily rely on tracheids for water conduction.

4. **Conclusion**:
- Since the question asks for the major xylary element in the wood of a gymnospermic plant, the correct answer is **tracheids**.

**Final Answer**: The major xylary element in the wood of a gymnospermic plant is **tracheids**.
