The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Pteridophytes**: Pteridophytes are vascular plants that reproduce via spores and include ferns and horsetails. They are the first terrestrial plants to possess vascular tissue. 2. **Identifying Key Features**: The main features of pteridophytes include: - Presence of vascular tissues (xylem and phloem). - The main plant body is sporophytic (dominant sporophyte generation). - Spores are produced by spore mother cells through the process of meiosis. 3. **Types of Spores**: - Majority of pteridophytes are **homosporous**, meaning they produce spores of the same type and size. - A minority of pteridophytes, such as Salvinia and Selaginella, are **heterosporous**, producing two different types of spores (macro and micro). 4. **Evaluating the Statements**: - **Homosporous**: This is true for the majority of pteridophytes. - **Heterosporous**: This is false as it applies only to some pteridophytes. - **Megaspore germinates into female gametophyte**: This is not a feature of the majority of pteridophytes. - **Precursor of seed habits**: This is also not applicable to the majority of pteridophytes. 5. **Conclusion**: The correct statement regarding the majority of pteridophytes is that they are **homosporous**. **Final Answer**: The true statement for the majority of pteridophytes is that they are **homosporous**. ---
