Ovule is called

Options

A. Megasporangium
B. Microsporangium
C. Integumented microsporangium
D. Integumented megasporangium.

Answer

**Step-by-Step Solution:**

1. **Understanding the Terms:**
- The question asks what an ovule is called. To answer this, we need to understand the terminology related to ovules in plants.

2. **Definition of Megasporangium:**
- An ovule is technically referred to as a megasporangium. This is because it is the structure that produces megaspores, which develop into the female gametophyte.

3. **Components of an Ovule:**
- An ovule consists of several parts:
- **Nucellus:** The central part that contains the megaspores.
- **Integuments:** These are protective layers surrounding the nucellus.
- **Funiculus:** The stalk that attaches the ovule to the placenta.

4. **Integumented Megasporangium:**
- Since the ovule has integuments (the protective coverings), it is more accurately described as an "integumented megasporangium." This term indicates that it is a megasporangium with protective layers.

5. **Micropyle:**
- The integuments also form an opening called the micropyle, which is crucial for fertilization as it allows the pollen tube to enter the ovule.

6. **Conclusion:**
- Based on the definitions and components discussed, the correct answer to the question "Ovule is called" is **integumented megasporangium**.

**Final Answer:**
- Ovule is called **integumented megasporangium**.
