Thalamus grows to enclose ovary and other parts arise above the ovary in condition

Options

A. Hypogynous
B. Perigynous
C. Epigynous
D. None of these

Answer

To answer the question, "Thalamus grows to enclose ovary and other parts arise above the ovary in condition," we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Flower Structure**:
- In flowering plants, the arrangement of floral parts (calyx, corolla, and androecium) in relation to the ovary is crucial for classification.

2. **Identify the Types of Arrangements**:
- There are three main types of arrangements based on the position of the ovary:
- **Hypogynous**: The ovary is positioned above the other floral parts.
- **Perigynous**: The floral parts are positioned at the same level as the ovary.
- **Epigynous**: The ovary is enclosed by the thalamus, and the other floral parts arise above it.

3. **Focus on the Given Condition**:
- The question specifies that the thalamus grows to enclose the ovary, which indicates that the ovary is positioned lower than the other floral parts.

4. **Conclusion**:
- This arrangement corresponds to the **epigynous** condition, where the ovary is inferior, meaning it is located below the other floral parts that arise above it.

5. **Examples of Epigynous Flowers**:
- Common examples of epigynous flowers include:
- Sunflower
- Cucumber
- Pumpkin

6. **Final Answer**:
- Therefore, the correct answer to the question is that this condition is called **epigynous**.
