The parenchyma tissue which forms the bulk of ovule where the sporogenous tissue is produced is:

Options

A. Embryo sac
B. Nucellus
C. Ovule
D. Megaspore mother cell

Answer

To answer the question, "The parenchyma tissue which forms the bulk of ovule where the sporogenous tissue is produced is:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of the Ovule**:
- The ovule is a small structure attached to the placenta via a stalk called the funicle. It is essential for the formation of seeds after fertilization.

2. **Identifying the Components of the Ovule**:
- The ovule consists of several parts: the outer and inner integuments, the micropyle, the chalaza, and the nucellus. The nucellus is the central part of the ovule.

3. **Recognizing the Role of Nucellus**:
- The nucellus is composed of parenchymatous cells and serves as the tissue where the sporogenous tissue is produced. This sporogenous tissue is crucial for the formation of megaspores and ultimately the female gametophyte.

4. **Defining the Terms**:
- The embryo sac is the female gametophyte that develops from the megaspores formed in the nucellus. However, the question specifically asks for the parenchyma tissue that forms the bulk of the ovule.

5. **Conclusion**:
- Since the nucellus is the mass of parenchymatous cells that forms the bulk of the ovule and is responsible for producing the sporogenous tissue, the correct answer is **nucellus**.

### Final Answer:
The parenchyma tissue which forms the bulk of the ovule where the sporogenous tissue is produced is the **nucellus**.
