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.
Which part of organ X contains gametes ?

Answer

To solve the question, we need to identify the parts of the flower described and determine which part contains the gametes.

### Step-by-Step Solution:

1. **Identify Organ X**: The question describes a "flask-shaped organ X" at the center of the flower. This organ is known as the **pistil**. The pistil is the female reproductive part of the flower.

**Hint**: Think about the structure of a flower and which part is responsible for female reproduction.

2. **Parts of the Pistil**: The pistil consists of three main parts:
- **Stigma**: The top part where pollen grains land.
- **Style**: The slender stalk that connects the stigma to the ovary.
- **Ovary**: The swollen base of the pistil that contains ovules.

**Hint**: Recall the three components of the pistil and their functions.

3. **Identify Organ Y**: The question mentions "little stalks Y having swollen tops." These are the **stamens**, which are the male reproductive parts of the flower. Each stamen consists of a filament (the stalk) and an anther (the swollen top where pollen is produced).

**Hint**: Remember that stamens are responsible for producing pollen, which contains male gametes.

4. **Locate Gametes in Organ X**: The question asks which part of organ X (the pistil) contains gametes. In the pistil, the **ovary** contains the ovules, which are the female gametes (eggs).

**Hint**: Focus on the function of the ovary in reproduction.

5. **Final Answer**: Therefore, the part of organ X (the pistil) that contains gametes is the **ovary**.

### Summary of the Solution:
The part of organ X (the pistil) that contains gametes is the **ovary**, as it houses the ovules (female gametes).
