A typical angiospermous ovule is attached to the placenta by means of a stalk called X. Body of the ovule fuses with X in the region called Y. Identify X and Y.

Options

A. `{:(X,Y),("Funicle","Hilum"):}`
B. `{:(X,Y),("Heilum","Funicle"):}`
C. `{:(X,Y),("Funicle","Micropyle"):}`
D. `{:(X,Y),("Hilum","Chalaza"):}`

Answer

To solve the question regarding the identification of X and Y in a typical angiospermous ovule, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of the Ovule**:
- A typical angiosperm ovule consists of several parts including the outer integument, inner integument, embryo sac, and other structures.

2. **Identifying the Stalk**:
- The stalk that attaches the ovule to the placenta is a key feature. This stalk-like structure is known as the **funicle**.
- Therefore, we identify **X** as **funicle**.

3. **Identifying the Fusion Region**:
- The region where the body of the ovule fuses with the stalk (funicle) is known as the **hilum**.
- Thus, we identify **Y** as **hilum**.

4. **Conclusion**:
- Based on the above identification, we conclude that **X is funicle** and **Y is hilum**.

### Final Answer:
- **X = Funicle**
- **Y = Hilum**
