Pericarp is formed of

Options

A. Ovule
B. Perianth
C. Ovary wall
D. Thalamus

Answer

To answer the question "Pericarp is formed of," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pericarp**:
- The pericarp is the part of a fruit that develops from the ovary wall after fertilization. It is essential to recognize that the pericarp is specifically related to the structure of fruits.

2. **Identifying the Components of a Flower**:
- In a flowering plant, after fertilization, various parts of the flower transform into different structures. For instance, the zygote develops into the embryo, and the ovule becomes the seed.

3. **Role of the Ovary**:
- The ovary is the part of the flower that contains the ovules. Once fertilization occurs, the ovary wall thickens and matures to form the fruit, which is known as the pericarp.

4. **Differentiation of Pericarp**:
- The pericarp itself is further divided into three layers:
- **Exocarp**: The outer layer.
- **Mesocarp**: The middle layer.
- **Endocarp**: The innermost layer that surrounds the seed.

5. **Eliminating Incorrect Options**:
- **Ovule**: This develops into the seed, not the pericarp.
- **Perianth**: This refers to the collective term for calyx and corolla, which are not involved in forming the pericarp.
- **Thalamus**: This is the thickened part of the stem that bears the floral organs, not a component of the pericarp.

6. **Conclusion**:
- Based on the understanding that the pericarp is derived from the ovary wall, we conclude that the correct answer is **ovary wall**.

### Final Answer:
The pericarp is formed of **ovary wall**.
