A mass of perenchymatous tissue forming the bulk of ovule is

Options

A. Obturator
B. Female gametophtye
C. Nucellus
D. Endosperm.

Answer

To solve the question "A mass of parenchymatous tissue forming the bulk of ovule is," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Components of the Ovule**:
- The ovule consists of several parts, including the nucellus, female gametophyte, and other structures such as the funiculus and integuments.

2. **Analyze the Options**:
- **Option A: Obturator**: This structure helps guide the pollen tube but does not form the bulk of the ovule.
- **Option B: Female Gametophyte**: This is a seven-celled structure that includes the egg apparatus and antipodal cells but is not the mass of parenchymatous tissue.
- **Option C: Nucellus**: This is the central part of the ovule and is indeed a mass of parenchymatous tissue. It contains the embryo sac and is the main bulk of the ovule.
- **Option D: Endosperm**: This is a nutritive tissue that develops after fertilization and is not part of the ovule's structure.

3. **Identify the Correct Answer**:
- Based on the analysis, the correct answer is **Option C: Nucellus**. It is the mass of parenchymatous tissue that forms the bulk of the ovule.

### Final Answer:
The mass of parenchymatous tissue forming the bulk of the ovule is **Nucellus**.
