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 typical angiospermous ovule, we need to identify two specific terms: X and Y. Here’s the step-by-step solution:

### Step-by-Step Solution:

1. **Understanding the Structure of the Ovule**:
- The ovule is a crucial part of the reproductive structure in flowering plants (angiosperms). It is attached to the placenta, which is the tissue within the ovary.

2. **Identifying the Stalk**:
- The ovule is connected to the placenta by a stalk. This stalk is referred to as **X**. In botanical terms, this stalk is called the **funiculus**.

3. **Identifying the Fusion Point**:
- The body of the ovule fuses with the funiculus at a specific region. This point of fusion is referred to as **Y**. The region where the ovule connects to the funiculus is called the **hilum**.

4. **Final Identification**:
- Therefore, we conclude:
- **X = Funiculus**
- **Y = Hilum**

### Summary:
- The stalk (X) that attaches the ovule to the placenta is called the **funiculus**.
- The region (Y) where the body of the ovule fuses with the funiculus is called the **hilum**.
