When fruit develops from the ovary it is called a false/true fruit.

Answer

**Step-by-Step Solution:**

1. **Understanding Fruit Development**: Fruits develop from the ovary of a flower after fertilization. This is a key point in distinguishing between true and false fruits.

2. **Definition of True Fruit**: A true fruit is one that develops solely from the ovary of the flower. This means that all the tissues of the fruit originate from the ovary, and the other floral parts (like petals and sepals) do not contribute to the fruit's structure.

3. **Definition of False Fruit**: A false fruit, on the other hand, develops from the ovary along with other floral parts, such as the thalamus (the thickened part of the stem where the flower parts are attached). In this case, the fruit includes tissues that are not derived from the ovary alone.

4. **Examples**:
- True Fruits: Examples include cherries, peaches, and tomatoes, where the fruit develops entirely from the ovary.
- False Fruits: Examples include apples and strawberries, where the thalamus contributes to the fruit's formation.

5. **Conclusion**: Since the question specifies that the fruit develops from the ovary, the correct answer is that it is a **true fruit**.

**Final Answer**: When fruit develops from the ovary, it is called a **true fruit**.
