Pistil is bicarpellary but ovary is unilocular and uniovuled in

Options

A. Lycopersicon
B. Scilla
C. Lepidium
D. Helianthus.

Answer

To solve the question regarding the characteristics of the pistil and ovary in flowering plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Pistil**: The female reproductive part of a flower, which can consist of one or more carpels.
- **Bicarpellary**: This means that the pistil consists of two carpels.
- **Unilocular**: This indicates that the ovary has one locule (chamber).
- **Uniovulated**: This means that there is only one ovule present in the ovary.

2. **Analyze the Options**:
- We have four options: Lycopersicon, Scylla, Lepidium, and Helianthus. We need to determine which of these has a bicarpellary pistil with a unilocular and uniovulated ovary.

3. **Evaluate Each Option**:
- **Lycopersicon**: This plant has a bicarpellary pistil but does not have a unilocular and uniovulated ovary.
- **Scylla**: This plant has two ovules, which disqualifies it from being the correct answer.
- **Lepidium**: This plant is also bicarpillary but has two ovules, so it does not meet the criteria.
- **Helianthus**: This plant belongs to the Asteraceae family and has a bicarpellary, unilocular, and uniovulated ovary.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Helianthus** (option 4), as it meets all the specified characteristics.

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