Transfusion tissue occurs in

Options

A. All embryophytes
B. Angiosperms
C. Gymnosperms
D. Ferns.

Answer

To determine where transfusion tissue occurs, we can follow these steps:

1. **Understand Transfusion Tissue**: Transfusion tissue, also known as hydrostereome, is a specialized type of tissue that plays a role in the conduction of water and nutrients.

2. **Identify the Types of Plants**: The question provides four options:
- All embryo fights
- Angiosperms
- Gymnosperms
- Spurs

3. **Analyze Each Option**:
- **All Embryophytes**: This term refers to all land plants, which is too broad and does not specifically indicate where transfusion tissue is found. Therefore, this option is incorrect.
- **Angiosperms**: These are flowering plants that typically have different types of vascular tissues. Transfusion tissue is not characteristic of angiosperms, making this option incorrect as well.
- **Gymnosperms**: This group includes non-flowering plants like pines and cycads. Transfusion tissue is specifically found around the vascular bundles in the leaves of gymnosperms, making this option correct.
- **Spurs**: This term does not refer to a type of plant with transfusion tissue and is therefore incorrect.

4. **Conclusion**: Based on the analysis, the correct answer is that transfusion tissue occurs in gymnosperms, specifically around the vascular bundles of their leaves.

**Final Answer**: Transfusion tissue occurs in gymnosperms.
