Which of these plants consist of a cymose inflorescence along with a syncarpous ovary?

Options

A. Onion
B. Potato
C. Soyabean
D. Both (A) and (B)

Answer

To solve the question of which plants consist of a cymose inflorescence along with a syncarpous ovary, let's analyze each option step by step.

### Step 1: Understand the Terms
- **Cymose Inflorescence**: This type of inflorescence has a limited growth pattern where the main axis ends in a flower, and subsequent flowers develop from lateral buds.
- **Syncarpous Ovary**: This refers to an ovary formed from multiple fused carpels.

### Step 2: Analyze Each Option
1. **Onion**:
- **Inflorescence**: Onion has a cymose inflorescence.
- **Ovary**: The ovary is syncarpous as the carpels are fused.
- **Conclusion**: Onion fits both criteria.

2. **Potato**:
- **Inflorescence**: Potato also exhibits a cymose inflorescence.
- **Ovary**: The ovary is syncarpous, meaning the carpels are fused.
- **Conclusion**: Potato fits both criteria.

3. **Soybean**:
- **Inflorescence**: Soybean has a racemose inflorescence, which means it has unlimited growth.
- **Ovary**: The ovary is syncarpous.
- **Conclusion**: Soybean does not fit the inflorescence criterion.

4. **Both A and B**:
- Since both onion and potato meet the criteria of having a cymose inflorescence and a syncarpous ovary, this option is also correct.

### Final Answer
The plants that consist of a cymose inflorescence along with a syncarpous ovary are **Onion and Potato** (Option D: Both A and B).
