Explain fertilization and how it leads to fruit and seed formation.

Answer 1

Fertilization: A process in which male and female gametes of a flower (pollen and egg respectively) fuse with each other to form a single celled zygote. This zygote develops into an embryo and finally into a new plant.

After the fertilization process, various parts of the plant show various changes. The sepal of the flower either withers away or remains attached even after the fertilization in certain plants. The stamen and anther of the flower withers away.
A fruit is formed when the ovary in the flower gets enlarged and the ovules present in the flowers forms the seeds.
