Naked seeds are present in

Options

A. Angiosperms
B. Gymnosperms
C. Spermatophyta
D. None of the above.

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Naked Seeds":**
- Naked seeds refer to seeds that are not enclosed within a fruit. This characteristic is crucial in identifying the type of plant group.

2. **Identifying Plant Groups:**
- The question provides four options: angiosperms, gymnosperms, spermatophyta, and none of the above. We need to analyze each option to determine where naked seeds are found.

3. **Analyzing Gymnosperms:**
- Gymnosperms are defined by their production of naked seeds. The term "gymnosperm" itself derives from Greek, where "gymno" means naked and "sperma" means seed.
- In gymnosperms, the ovules are exposed and not enclosed within an ovary. They are typically found on the surface of cone scales.

4. **Analyzing Angiosperms:**
- Angiosperms, or flowering plants, produce seeds that are enclosed within a fruit. This means their seeds are not naked.
- The ovules in angiosperms are enclosed within the ovary, which develops into the fruit after fertilization.

5. **Analyzing Spermatophyta:**
- Spermatophyta is a broader category that includes both gymnosperms and angiosperms. Therefore, it cannot be the correct answer since it encompasses plants with both naked and enclosed seeds.

6. **Conclusion:**
- Based on the analysis, the only group that exclusively has naked seeds is gymnosperms. Therefore, the correct answer to the question is gymnosperms.

**Final Answer:**
- Naked seeds are present in **gymnosperms**.
