Which fo the following change does not occurs in ovary as a result of sexual reproductin ?

Options

A. ovary wall - pericarip
B. ovary - fruit
C. ovule - fruit wall
D. integument - speed coat

Answer

To answer the question "Which of the following changes does not occur in the ovary as a result of sexual reproduction?", we need to analyze the changes that typically occur in the ovary during and after the process of sexual reproduction in flowering plants.

### Step-by-Step Solution:

1. **Understanding Sexual Reproduction in Flowering Plants**:
- Sexual reproduction involves the fusion of male and female gametes, leading to the formation of a zygote.

2. **Key Events in the Ovary**:
- **Syngamy**: This is the fusion of the sperm cell with the egg cell, resulting in the formation of a diploid zygote (2N).
- **Triple Fusion**: This involves the fusion of one sperm cell with two polar nuclei, resulting in the formation of the triploid endosperm.

3. **Changes in the Ovary Post-Fertilization**:
- After fertilization, the ovary undergoes significant changes:
- The ovary wall transforms into the pericarp, which is the fruit wall.
- The ovule, which is located within the ovary, develops into a seed.
- The integuments of the ovule form the seed coat.

4. **Identifying the Incorrect Change**:
- The question asks for a change that does NOT occur in the ovary as a result of sexual reproduction.
- The changes that do occur include:
- The ovary wall becoming the pericarp (fruit wall).
- The ovule developing into a seed.
- The integuments forming the seed coat.
- Therefore, any statement suggesting that the ovary does not undergo these transformations would be incorrect.

5. **Conclusion**:
- The change that does not occur in the ovary as a result of sexual reproduction is related to the ovule not turning into a seed, as this is a key transformation that does occur.

### Final Answer:
The change that does not occur in the ovary as a result of sexual reproduction is that the ovule does not convert into a seed.
