Transfusion tissue is present in the leaves of

Options

A. Pinus
B. Dryopteris
C. Cycas
D. Both (1) & (3)

Answer

To solve the question regarding the presence of transfusion tissue in the leaves of certain plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Transfusion Tissue**:
- Transfusion tissue is a specialized type of tissue found in the leaves of certain plants, particularly gymnosperms. It plays a role in the conduction of water and nutrients.

2. **Identify the Options**:
- The options given are:
1. Pinus
2. Dryopteris
3. Cyclus
4. Both first and second (Pinus and Dryopteris)

3. **Determine the Type of Plants**:
- Pinus and Cyclus are both gymnosperms, while Dryopteris is a fern (which is a type of pteridophyte). Transfusion tissue is primarily found in gymnosperms.

4. **Analyze Each Option**:
- **Pinus**: As a gymnosperm, it possesses transfusion tissue in its leaves.
- **Dryopteris**: Being a fern, it does not have transfusion tissue.
- **Cyclus**: Also a gymnosperm, it has transfusion tissue in its leaves.
- **Both first and second**: This option is incorrect since Dryopteris does not have transfusion tissue.

5. **Conclusion**:
- Since both Pinus and Cyclus have transfusion tissue, the correct answer is option 4: "Both first and second" (which refers to Pinus and Cyclus).

### Final Answer:
The transfusion tissue is present in the leaves of both Pinus and Cyclus.
