Gibberellins cause parthenocarpy in some type of fruits.

Answer

### Step-by-Step Solution:

1. **Understanding Parthenocarpy**:
- Parthenocarpy is the process of fruit development without fertilization. This means that the fruit can develop without the need for seeds.
- Fruits that develop through parthenocarpy are typically seedless.

2. **Role of Gibberellins**:
- Gibberellins are a type of plant hormone (phytohormone) that play various roles in plant growth, including seed germination and flowering.
- However, gibberellins are not primarily responsible for inducing parthenocarpy.

3. **Identifying the Correct Hormone**:
- The hormone that is mainly responsible for promoting parthenocarpy is Auxin, not gibberellins.
- Auxin helps in the development of seedless fruits by stimulating the growth of the ovary into a fruit without fertilization.

4. **Conclusion**:
- Therefore, the statement "Gibberellins cause parthenocarpy in some types of fruits" is incorrect.
- The correct hormone that induces parthenocarpy is Auxin.
