Answer:
-lock-
Fertilization is the process of fusion of male and female gamete to form a zygote. The post-fertilisation changes that lead to the formation of fruit in plants are as follows:
- The zygote that is formed divides several times to form an embryo within the ovule.
- The ovule develops a tough coat and is converted into a seed.
- The ovary swells and ripens to form fruit.
- The other parts of a flower like petals, sepals, stamen, style and stigma shrivel and fall off.
