Integumented megasporangium is

Options

A. ovule
B. pollen sac
C. pollen grain
D. embryo sac

Answer

To answer the question "Integumented megasporangium is:", we need to analyze the options provided and understand the concept of megasporangium and its integuments.

### Step-by-Step Solution:

1. **Understanding Megasporangium**:
- A megasporangium is a structure that produces megaspores, which are involved in the formation of female gametes in plants.

2. **Identifying Integuments**:
- Integuments are layers of tissue that surround and protect the megasporangium. They play a crucial role in the development of the ovule.

3. **Connecting Megasporangium and Integuments**:
- The integumented megasporangium refers to a megasporangium that is surrounded by integuments. This structure is essential for the protection and development of the female gametophyte.

4. **Evaluating the Options**:
- **Option A: Ovule** - This is the correct answer. The ovule is the integumented megasporangium that contains the female gametophyte.
- **Option B: Pollen sac** - This is incorrect as pollen sacs are related to microsporangium, not megasporangium.
- **Option C: Pollen grain** - This is also incorrect as pollen grains are part of the microsporogenesis process.
- **Option D: Ambrosac** - This is incorrect because it is not covered by integuments.

5. **Conclusion**:
- Based on the analysis, the integumented megasporangium is the **ovule**.

### Final Answer:
The integumented megasporangium is **ovule**.
