In some plants thalamus contributes to fruit formation.Such fruits are termed as:

Options

A. False fruits
B. Aggregate fruits
C. True fruits
D. Parthenocarpic fruits

Answer

To solve the question regarding the type of fruit formed when the thalamus contributes to fruit formation, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of the Thalamus**:
- The thalamus, also known as the receptacle, is the part of the flower that bears all the floral organs including petals, sepals, stamens, and carpels.

2. **Identify the Components of a Fruit**:
- In flowering plants (angiosperms), the fruit typically develops from the ovary of the flower after fertilization. The ovary contains ovules that develop into seeds.

3. **Differentiate Between True and False Fruits**:
- A true fruit is formed solely from the ovary after fertilization. In contrast, a false fruit (or accessory fruit) includes additional floral parts, such as the thalamus, in its structure.

4. **Examples of False Fruits**:
- An example of a false fruit is the apple. In apples, the core (which is the true fruit) is surrounded by the fleshy part that develops from the thalamus, not the ovary.

5. **Conclusion**:
- Therefore, when the thalamus contributes to the formation of the fruit, such fruits are termed as **false fruits**.

### Final Answer:
The fruits in which the thalamus contributes to fruit formation are termed as **false fruits**.
