Which of the following are correct about pteridophytes ?
I. The sporophyte bear sporangia formed on sporophylls.
II. They are frequently grown as ornamentals.
III. They are the first terrestrial plants to forms seeds.
IV . Vascular tissues are present in pteriodophytes.
V. They do not form embryo .

Options

A. V and IV
B. I, II and IV
C. III, IV and V
D. I and II

Answer

To determine which statements about pteridophytes are correct, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement I: The sporophyte bears sporangia formed on sporophylls.**
- **Analysis**: This statement is correct. In pteridophytes, the sporophyte generation produces sporangia, which are often located on specialized leaves known as sporophylls. These sporangia are responsible for producing spores.
- **Conclusion**: Correct.

2. **Statement II: They are frequently grown as ornamentals.**
- **Analysis**: This statement is also correct. Many pteridophytes, particularly ferns, are commonly cultivated as ornamental plants due to their attractive foliage.
- **Conclusion**: Correct.

3. **Statement III: They are the first terrestrial plants to form seeds.**
- **Analysis**: This statement is incorrect. Pteridophytes do not produce seeds; they reproduce via spores. The first terrestrial plants to form seeds are gymnosperms and angiosperms.
- **Conclusion**: Incorrect.

4. **Statement IV: Vascular tissues are present in pteridophytes.**
- **Analysis**: This statement is correct. Pteridophytes possess vascular tissues, including xylem and phloem, which allow for the transport of water, nutrients, and food throughout the plant.
- **Conclusion**: Correct.

5. **Statement V: They do not form an embryo.**
- **Analysis**: This statement is incorrect. Pteridophytes do form embryos. The zygote develops into an embryo within the female gametophyte, which is a precursor to seed formation.
- **Conclusion**: Incorrect.

### Summary of Correct Statements:
- The correct statements about pteridophytes are I, II, and IV.

### Final Answer:
The correct options are I, II, and IV.
