Gametophyte embeded in sporophyte in :-

Options

A. Bryophyta
B. Pteridophyta
C. Cryptogams
D. Spermatophyta

Answer

To solve the question "Gametophyte embedded in sporophyte in:", we will analyze the options provided and understand the relationship between gametophytes and sporophytes in different plant groups.

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Gametophyte**: The haploid phase of the plant life cycle that produces gametes (sperm and eggs).
- **Sporophyte**: The diploid phase that produces spores through meiosis.

2. **Identify the Plant Groups**:
- **Bryophyta**: This group includes mosses and liverworts. In bryophytes, the gametophyte is the dominant and independent phase, while the sporophyte is often dependent on the gametophyte.
- **Pteridophyta**: This group includes ferns. In pteridophytes, the sporophyte is dominant, but the gametophyte is independent and free-living.
- **Cryptogams**: This term generally refers to non-flowering plants that reproduce via spores, including both bryophytes and pteridophytes.
- **Spermatophyta**: This group includes seed plants, which are divided into gymnosperms and angiosperms. In these plants, the gametophytes are reduced and embedded within the sporophyte.

3. **Analyze the Options**:
- In **Bryophyta**, the gametophyte is independent and dominant.
- In **Pteridophyta**, the gametophyte is also independent.
- **Cryptogams** is a broad term and does not specify the relationship clearly.
- In **Spermatophyta**, the gametophyte is not independent; it is embedded within the sporophyte.

4. **Conclusion**:
- The correct answer is **Spermatophyta**, as in this group, the gametophyte is reduced and embedded within the sporophyte.

### Final Answer:
The correct answer is **Spermatophyta**.
