Describe the post-fertilization changes in a flower.

(N/A) Fertilization is the process of the fusion of the male and female gametes to form a diploid zygote.
After fertilization,the zygote undergoes mitotic divisions to develop into an embryo.
The fertilized ovule transforms into a seed,which contains the embryo protected by a seed coat.
Simultaneously,other floral parts such as sepals,petals,and stamens usually wither and fall off.
The ovary undergoes significant changes,enlarging and ripening to develop into a fruit.
The ovary wall develops into the pericarp,which serves as the protective covering of the fruit.
