In pteridophytes, reduction division takes place in :-

Options

A. Prothallus is formed
B. Sex organs are formed
C. Spores are formed
D. Gametes are formed

Answer

To solve the question "In pteridophytes, reduction division takes place in:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pteridophytes**:
- Pteridophytes are a group of vascular plants that reproduce via spores. They include ferns, horsetails, and clubmosses.

2. **Identifying the Main Plant Body**:
- In pteridophytes, the dominant phase of the life cycle is the sporophyte phase, which is diploid (2n).

3. **Sporophylls and Sporangia**:
- The leaves of the sporophyte are called sporophylls. These sporophylls bear structures called sporangia.

4. **Reduction Division**:
- Reduction division, or meiosis, occurs in the sporangia. This process leads to the formation of haploid spores (n) from the diploid sporophyte.

5. **Formation of Spores**:
- The spores produced by meiosis in the sporangia will eventually develop into the gametophyte stage, which is haploid.

6. **Evaluating the Options**:
- **Prothalus formed**: Incorrect, as prothalus is the gametophyte stage.
- **Sex organs formed**: Incorrect, as sex organs develop in the gametophyte stage.
- **Spores are formed**: Correct, as reduction division occurs in the sporangia to produce spores.
- **Gametes are formed**: Incorrect, as gametes are produced from the gametophyte, not directly from reduction division.

7. **Conclusion**:
- Therefore, the correct answer is that reduction division takes place in the formation of spores in pteridophytes.

### Final Answer:
Reduction division takes place in the formation of spores in pteridophytes.
