Which structure of ovule, takes part in storage of food ?

Options

A. Integuments
B. Nucellus
C. Embryosac
D. Micropyle

Answer

To answer the question "Which structure of ovule takes part in storage of food?", we can break down the information step by step.

### Step-by-Step Solution:

1. **Understanding the Ovule Structure**: The ovule consists of several structures including integuments, funiculus, micropyle, nucellus, and embryo sac. Each of these has specific roles.

2. **Identifying the Structures**:
- **Integuments**: These are the protective coverings of the ovule. They do not store food.
- **Funiculus**: This is the stalk that attaches the ovule to the placenta. It also does not store food.
- **Micropyle**: This is a small opening in the ovule, which allows for the entry of pollen. It does not store food.
- **Nucellus**: This is a mass of cells within the ovule that contains the reserve food material.
- **Embryo Sac**: This is the female gametophyte that develops within the ovule and contains the egg cell and other cells.

3. **Focusing on Nucellus**: The structure that is primarily responsible for the storage of food in the ovule is the **nucellus**. It contains abundant reserve food material that supports the developing embryo after fertilization.

4. **Conclusion**: Therefore, the correct answer to the question is that the **nucellus** is the structure of the ovule that takes part in the storage of food.

### Final Answer:
The structure of the ovule that takes part in the storage of food is the **nucellus**.
