There is a great variation in the nature of pericarp in

Options

A. Berries
B. Dry fruits
C. Fleshy fruits
D. Indehiscent dry fruits

Answer

To address the question regarding the variation in the nature of pericarp, we can break down the solution into several steps:

### Step-by-Step Solution:

1. **Definition of Pericarp**:
- The pericarp is the part of a fruit that develops from the ovary wall after fertilization. It consists of three layers: the exocarp (outer layer), mesocarp (middle layer), and endocarp (inner layer).

**Hint**: Remember that the pericarp is formed from the ovary wall and has three distinct layers.

2. **Types of Fruits**:
- Fruits can be classified into two main categories: fleshy fruits and dry fruits. Fleshy fruits have a juicy and edible outer layer, while dry fruits do not have such characteristics.

**Hint**: Distinguish between fleshy and dry fruits based on their texture and edibility.

3. **Variation in Fleshy Fruits**:
- Fleshy fruits, such as lychee and mango, exhibit significant variation in their pericarp structure. The edible part of these fruits is derived from the mesocarp and sometimes the endocarp, leading to diverse forms and textures.

**Hint**: Focus on examples of fleshy fruits to understand how their pericarp varies.

4. **Variation in Dry Fruits**:
- Dry fruits, like cashew nuts, do not open at maturity and often have a less varied structure in their pericarp compared to fleshy fruits. The seeds remain enclosed within the fruit.

**Hint**: Consider how the structure of dry fruits limits variation in pericarp compared to fleshy fruits.

5. **Conclusion**:
- Based on the analysis, the most significant variation in the nature of pericarp is found in fleshy fruits. Therefore, the correct answer to the question is that fleshy fruits exhibit the greatest variation in pericarp structure.

**Hint**: Summarize your findings by emphasizing the differences in pericarp variation between fleshy and dry fruits.

### Final Answer:
The correct option is that fleshy fruits show the greatest variation in the nature of pericarp.
