Which of the following statement best describes an ovule ?

Options

A. Integumented dehiscent megasporangium.
B. Integumented indehiscent microsporangia.
C. Integumented indehiscent megasporangium.
D. Non-integumented indehiscent megasporangium.

Answer

To determine which statement best describes an ovule, we can analyze the characteristics and definitions related to ovules in flowering plants. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding the Structure of an Ovule**:
- An ovule is a structure found in seed plants that develops into a seed after fertilization. It contains the female gametophyte, which is crucial for reproduction.

2. **Components of an Ovule**:
- An ovule typically contains several key components:
- 1 egg cell
- 2 synergids
- 3 antipodal cells
- 2 polar nuclei
- These components are part of the female gametophyte, also known as the embryo sac.

3. **Integuments**:
- The ovule is surrounded by protective layers called integuments. These integuments play a vital role in protecting the developing ovule.

4. **Types of Megasporangia**:
- The terms "dehiscent" and "indehiscent" refer to whether the structure releases its contents (seeds) or not.
- Dehiscent means it opens up to release seeds, while indehiscent means it does not open and retains the seeds.

5. **Evaluating the Options**:
- **Option A**: Describes the ovule as "oval shape with 8 cells present." This is partially correct but does not encompass the protective nature of integuments.
- **Option B**: "Integumented Dehiscent Megasporangia" is incorrect because ovules are not dehiscent; they do not release seeds.
- **Option C**: "Integumented Indehiscent Megasporangia" is correct as it captures the protective integuments and the fact that ovules do not release seeds.
- **Option D**: "Non-integumented Indehiscent Megasporangium" is incorrect because integuments are indeed present in ovules.

6. **Conclusion**:
- The best description of an ovule is **Option C: Integumented Indehiscent Megasporangia**.

### Final Answer:
**Option C: Integumented Indehiscent Megasporangia**
