The dlask-shaped organ X at the centre of a flower is surrounded by a number of little stalks Y having swollen tops which lie just inside the ring of petals.
Out of X and Y, which one is the female part of flower ?

Answer

To determine which part of the flower is the female part, we can analyze the given information step by step.

### Step-by-Step Solution:

1. **Identify the Structures**:
- The question describes two structures:
- **X**: A flask-shaped organ located at the center of the flower.
- **Y**: Little stalks with swollen tops surrounding the flask-shaped organ.

2. **Understanding Flower Anatomy**:
- In flowering plants, the female part of the flower is known as the **gynoecium** or **pistil**. It typically consists of three main parts:
- **Stigma**: The top part that receives pollen.
- **Style**: The stalk that connects the stigma to the ovary.
- **Ovary**: The swollen base that contains ovules.

3. **Analyzing Structure X**:
- The description of **X** as a "flask-shaped organ" aligns with the structure of the gynoecium (pistil), which is indeed flask-shaped and located at the center of the flower.

4. **Analyzing Structure Y**:
- The description of **Y** as "little stalks having swollen tops" indicates that these are likely the male parts of the flower, known as the **stamens**. The swollen tops are the **anthers**, which contain pollen grains (male gametes).

5. **Conclusion**:
- Based on the analysis, **X** is the female part of the flower (the pistil), while **Y** represents the male part (the stamens). Therefore, the answer to the question is that **X is the female part of the flower**.

### Final Answer:
**X is the female part of the flower.**
