The integumented megasporangiate is :-

Options

A. Locule
B. Ovule
C. Pollen sac
D. Embryo sac

Answer

To answer the question "The integumented megasporangiate is:", we need to analyze the options and understand the concept of integumented megasporangium.

### Step-by-Step Solution:

1. **Understanding Megasporangium**:
- The megasporangium is a structure in plants that produces megaspores, which eventually develop into female gametophytes.

2. **Identifying Integument**:
- The integument is a protective layer surrounding the megasporangium. In flowering plants, this structure is crucial for the development of seeds.

3. **Recognizing the Role of Ovules**:
- The ovule is the structure that contains the integumented megasporangium. It consists of the megasporangium (nucellus) surrounded by one or two layers of integument.

4. **Connecting to the Options**:
- The options provided are:
1. Locule
2. Orbital
3. Polensec
4. Intersect
- From the understanding of the terms, the correct association is that the integumented megasporangium is equivalent to the ovule.

5. **Identifying the Correct Answer**:
- The term "orbital" refers to the megasporangium, which is also known as the ovule when it is integumented. Therefore, the integumented megasporangiate is best described as the ovule.

6. **Final Answer**:
- The integumented megasporangiate is: **Orbital (Option 2)**.
