Options

B. absence of ovary
C. absence of ovule
D. absence of sieve cells.

Answer

To understand how gymnosperms differ from angiosperms, we can break down the key differences step by step:

### Step-by-Step Solution:

1. **Definition of Gymnosperms and Angiosperms**:
- Gymnosperms are a group of seed-producing plants that do not form flowers or fruits. Their seeds are often exposed or "naked."
- Angiosperms, on the other hand, are flowering plants that produce seeds enclosed within a fruit.

2. **Seed Production**:
- Both gymnosperms and angiosperms produce seeds. Therefore, the option stating the "absence of seed" is incorrect for distinguishing between the two.

3. **Presence of Ovary**:
- Gymnosperms lack ovaries. This absence means they do not produce fruits, as fruits develop from the ovary after fertilization in angiosperms.
- Angiosperms possess ovaries, which allow them to produce fruits.

4. **Conclusion**:
- The primary difference between gymnosperms and angiosperms lies in the presence or absence of an ovary. Gymnosperms do not have ovaries, making them non-flowering plants, while angiosperms have ovaries and are classified as flowering plants.

### Final Answer:
Gymnosperms are different from angiosperms in the absence of ovary.
