In pteridophytes, sporophyll are borne on `:`

Options

A. sporophytes
B. gametophytes
C. roots
D. sporangia

Answer

To answer the question "In pteridophytes, sporophyll are borne on:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pteridophytes**:
- Pteridophytes include plants like ferns and horsetails, which are the first terrestrial plants to develop vascular tissues (xylem and phloem).

2. **Identifying the Main Plant Body**:
- In pteridophytes, the main plant body is the sporophyte. This is the diploid phase of the plant life cycle.

3. **Defining Sporophylls**:
- Sporophylls are specialized leaves that bear sporangia, which are structures that produce spores.

4. **Location of Sporophylls**:
- Since sporophylls are part of the sporophyte generation, they are borne on the sporophyte itself. They can be found in the form of leaves or leaf-like appendages.

5. **Role of Sporophylls**:
- In the sporophyte, spore mother cells undergo meiosis within the sporangia located on the sporophylls, leading to the production of spores.

6. **Conclusion**:
- Therefore, the correct answer to the question is that sporophylls are borne on the sporophyte.

### Final Answer:
In pteridophytes, sporophylls are borne on the sporophyte.
