The ovule is attached to placenta by means of a stalk called funicle/hilum.

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of the Ovule:**
- The ovule is a small structure that is crucial for reproduction in flowering plants. It is also referred to as the megasporangium.

2. **Attachment of the Ovule:**
- The ovule is attached to the placenta, which is the part of the ovary where ovules are found. This attachment occurs via a stalk-like structure.

3. **Identifying the Stalk:**
- The stalk that connects the ovule to the placenta is known as the **funicle**.

4. **Understanding the Hilum:**
- The hilum is the region where the ovule is fused with the funicle. It is not the name of the stalk but rather the point of attachment.

5. **Protective Layers of the Ovule:**
- The ovule is covered by two protective layers called **integuments**. There are typically two outer integuments and one inner integument.

6. **Micropyle and Chalazal End:**
- At one end of the ovule, there is a small opening called the **micropyle**, which is where the pollen tube enters during fertilization. The opposite end is referred to as the **chalazal end**, which represents the basal part of the ovule.

7. **Diagram Representation:**
- A diagram of the ovule typically shows the chalazal pole at one end and the micropylar pole at the other. The funicle connects to the hilum, and the embryo sac is contained within the nucellus.
