Fruits are not formed in gymnosperms because :

Options

A. they are seedless
B. they are not pollinated
C. the process of fertilization does not occur
D. they have no ovary

Explanation

**Step-by-Step Solution:**

1. **Understanding Fruits and Their Formation:**
- Fruits are formed from the ovary of a flower after pollination and fertilization occur. The ovary matures into a fruit that encloses the seeds.

2. **Role of the Ovary:**
- The ovary contains ovules, which develop into seeds upon fertilization. The ovary itself is crucial for fruit development.

3. **Characteristics of Gymnosperms:**
- Gymnosperms are a group of plants that do not have flowers or ovaries. Instead, they produce seeds that are not enclosed within a fruit.

4. **Comparison with Angiosperms:**
- In angiosperms (flowering plants), the ovary is present and develops into a fruit. In contrast, gymnosperms lack this structure.

5. **Conclusion:**
- Since gymnosperms do not have an ovary, they cannot produce fruits. The ovules in gymnosperms are located directly on the surface of cones, not enclosed within an ovary.

**Final Answer:**
Fruits are not formed in gymnosperms because they do not have an ovary.
