Select true statement `//` feature for majority of the pteridophytes.

Options

A. Homosporous
B. Heterosporous
C. Megaspores germinate into female gametophyte
D. Precursor of seed habits

Answer

**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**.
