Answer

To determine how many plants among soybean, brinjal, tulip, rose, cucumber, chili, and guava have a superior ovary, we need to classify each plant based on the position of the ovary relative to other floral parts. Here’s a step-by-step solution:

### Step 1: Understand the Types of Ovary Positions
- **Superior Ovary**: The ovary is positioned above the other floral parts (hypogynous).
- **Half Superior Ovary**: The ovary is in the center, with floral parts at the same level (perigynous).
- **Inferior Ovary**: The ovary is enclosed by the thalamus, with floral parts above it (epigynous).

### Step 2: Analyze Each Plant
1. **Soybean**: Classified as half inferior (perigynous).
2. **Brinjal**: Classified as superior ovary (hypogynous).
3. **Tulip**: Classified as superior ovary (hypogynous).
4. **Rose**: Classified as half inferior (perigynous).
5. **Cucumber**: Classified as inferior (epigynous).
6. **Chili**: Classified as inferior (epigynous).
7. **Guava**: Classified as inferior (epigynous).

### Step 3: Count the Plants with Superior Ovary
From the analysis:
- **Brinjal**: Superior ovary
- **Tulip**: Superior ovary

Thus, there are **2 plants (Brinjal and Tulip)** that have a superior ovary.

### Final Answer
The number of plants with a superior ovary is **2**.
