Which of the following contains abundant reserve food material?

Options

A. Nucellus
B. Nucleus
C. Chalazal end
D. Micropylar end

Answer

To determine which of the following contains abundant reserve food material, let's analyze the options provided: Neucellus, Nucleus, Chalazal, and Micropyle.

### Step-by-Step Solution:

1. **Understanding the Structures**:
- **Nucellus**: This is a part of the ovule, also known as the megasporangium. It is responsible for housing the female gametophyte (embryosac) and is where the reserve food material is stored.
- **Nucleus**: This refers to the organelle within a cell that contains genetic material (DNA). It does not store food.
- **Chalazal**: This is the region of the ovule opposite the micropyle. It does not serve as a storage site for food.
- **Micropyle**: This is the opening in the ovule through which the pollen tube enters. It does not contain reserve food material.

2. **Identifying the Correct Option**:
- Among the options, the **Nucellus** is specifically known for containing abundant reserve food material that nourishes the developing embryo.

3. **Conclusion**:
- The correct answer is **Nucellus**, as it contains abundant reserve food material.

### Final Answer:
The structure that contains abundant reserve food material is **Nucellus**.
