Which of the following tissue is present in the leaves of Pinus and serve to conduct water and food

Options

A. Xylem
B. Phloem
C. Transfussion tissue
D. Conducting tissue

Answer

To answer the question regarding which tissue is present in the leaves of Pinus and serves to conduct water and food, we can follow these steps:

### Step-by-Step Solution

1. **Identify the Types of Tissues**: First, we need to understand the types of tissues mentioned in the options: xylem, phloem, transfusion tissue, and conducting tissue.

2. **Understand the Function of Each Tissue**:
- **Xylem**: Primarily responsible for the conduction of water and minerals from the roots to the leaves.
- **Phloem**: Responsible for the transport of food (sugars) produced during photosynthesis from the leaves to other parts of the plant.
- **Transfusion Tissue**: A specialized tissue found in the leaves of gymnosperms, which is a combination of xylem and phloem that aids in the conduction of both water and food.
- **Conducting Tissue**: A general term that could refer to both xylem and phloem but is not specific.

3. **Focus on Pinus**: Since the question specifically mentions the leaves of Pinus, we need to look at the unique characteristics of its leaves. Pinus, being a gymnosperm, has a unique structure in its leaves.

4. **Identify the Correct Tissue**: In the leaves of Pinus, the transfusion tissue is a prominent feature. This tissue is a modified form of the vascular bundle that includes both xylem and phloem components, allowing it to effectively conduct both water and food.

5. **Conclusion**: Therefore, the correct answer to the question is **transfusion tissue**, as it serves to conduct both water and food in the leaves of Pinus.

### Final Answer
The tissue present in the leaves of Pinus that serves to conduct water and food is **transfusion tissue**.
