Juicy hair-like structures observed in the lemon fruit develop form

Options

A. mesocarp and endocarp
B. exocarp
C. mesocarp
D. endocarp

Explanation

To answer the question about the juicy hair-like structures observed in the lemon fruit and their development, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structures**: The question asks about the "juicy hair-like structures" found in lemon fruit. These structures are known as placental hairs.

2. **Understand Fruit Anatomy**: In a fruit, there are three main layers:
- Exocarp (outer layer)
- Mesocarp (middle layer)
- Endocarp (inner layer)

3. **Locate the Endocarp**: The juicy hair-like structures, or placental hairs, are specifically found within the fruit. They develop from the endocarp, which is the innermost layer of the fruit surrounding the seeds.

4. **Confirm the Development**: The placental hairs are derived from the endocarp tissue, which is located just inside the pericarp (the entire fruit wall) and surrounds the seeds.

5. **Select the Correct Option**: Based on the above understanding, the correct answer to the question is that the juicy hair-like structures in the lemon fruit develop from the endocarp. Therefore, option number 4 is the right choice.

6. **Additional Information**: It is also useful to note that lemon fruit is classified as a Hesperidium, which is a type of berry with multiple chambers, each containing seeds and placental hairs.

### Final Answer:
The juicy hair-like structures observed in the lemon fruit develop from the endocarp.
