Thalamus or pedicel contribute in the formation of false fruit in
A) Fig B) Cashewnut
C) Apple D) Strawberrry
E) Guava

Options

A. AC only
B. BCD only
C. CD only
D. ACDE only

Answer

To determine which of the listed fruits has the thalamus or pedicel contributing to the formation of a false fruit, we can analyze each option step by step.

### Step 1: Understand the Concept of False Fruit
- A false fruit, also known as a pseudocarp, is a fruit that develops from parts of the flower other than the ovary. This can include the thalamus (receptacle) or pedicel.

### Step 2: Analyze Each Option
- **A) Fig**: The fig is a true fruit that develops from the ovary. It does not have a significant contribution from the thalamus or pedicel.

- **B) Cashew nut**: The cashew nut is a false fruit. The cashew apple (the fleshy part) develops from the thalamus, while the nut itself is the true fruit (the ovary). Therefore, the thalamus contributes to the formation of the false fruit.

- **C) Apple**: The apple is also a false fruit. The fleshy part of the apple is derived from the thalamus, while the core contains the seeds, which develop from the ovary.

- **D) Strawberry**: The strawberry is another example of a false fruit. The fleshy part of the strawberry is formed from the receptacle (thalamus), while the actual fruits (achenes) are the small seeds on the surface.

- **E) Guava**: The guava is a true fruit that develops solely from the ovary and does not involve the thalamus or pedicel in its formation.

### Step 3: Conclusion
From the analysis:
- **False fruits**: Cashew nut, Apple, Strawberry
- **True fruits**: Fig, Guava

Thus, the correct answer to the question is **B) Cashew nut**.
