Which of the following parts are used for the development of fruit in mango and coconut?

Options

A. Polycarpellary superior ovaries and is one seeded
B. Polycarpellary superior ovaries and are many seeded
C. Monocarpellary superior ovaries and are one seeded
D. Monocarpellary inferior ovaries and are many seeded

Answer

To determine which parts are used for the development of fruit in mango and coconut, we can analyze the structure of these fruits and their reproductive parts. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Identify the Fruit Structure**:
- Both mango and coconut are fruits that contain seeds. The structure of these fruits includes three main layers: the outer pericarp, the fleshy mesocarp, and the inner endocarp.

2. **Understand the Layers**:
- **Pericarp**: This is the outer layer of the fruit. In mango, it is thin, while in coconut, it can be more fibrous.
- **Mesocarp**: This is the fleshy part of the fruit. In mango, it is the juicy, edible part that we consume. In coconut, it is the white flesh.
- **Endocarp**: This is the innermost layer that surrounds the seed. In both mango and coconut, the endocarp is hard and stony, protecting the seed inside.

3. **Examine the Ovary Type**:
- Both mango and coconut have a **superior ovary**. This means that the ovary is located above the attachment point of the other floral parts (sepals and petals).

4. **Identify the Number of Carpels**:
- Both mango and coconut have a single carpel, which means they are classified as **monocarpillary**. This indicates that there is only one ovule and hence one seed in each fruit.

5. **Conclusion**:
- The correct answer is that the development of fruit in mango and coconut involves a **monocarpillary superior ovary** with one seed.

### Final Answer:
The parts used for the development of fruit in mango and coconut are the **monocarpillary superior ovary**.
