If a fruit is formed without fertilisation of ovary it is called

Answer

### Step-by-Step Solution:

1. **Understanding Fertilization**: Fertilization is the process where male and female gametes fuse to form a zygote. This is a crucial step in the formation of seeds and subsequently fruits.

2. **Identifying the Scenario**: The question specifies that a fruit is formed without the fertilization of the ovary. This means that the usual process of fertilization, which leads to the development of seeds, does not occur.

3. **Defining the Fruit**: A fruit is typically defined as the mature ovary of a flower, which usually contains seeds formed after fertilization.

4. **Considering the Alternative Process**: When a fruit develops without fertilization, it indicates that the ovary has matured and developed into a fruit without the involvement of fertilization.

5. **Naming the Process**: The process by which a fruit forms without fertilization is known as **Parthenocarpy**. This results in the formation of seedless fruits.

6. **Conclusion**: Therefore, if a fruit is formed without the fertilization of the ovary, it is called **Parthenocarpy**.
