Post-Fertilization (Seed and Fruit Formation)
Process:
After fertilization occurs, the resulting zygote undergoes cell division to form an embryo. The embryo then develops into a seed, which contains an embryo, a food reserve, and protective layers. Simultaneously, the remaining cells of the flower develop into the fruit, which serves as a protective structure for the developing seeds.
Key Events:
Ovulation: The release of a mature egg from the ovary.
Fertilization: The union of the sperm and egg to form a zygote.
Embryogenesis: The growth and development of the embryo from the zygote.
Fruit development: The surrounding tissue of the flower converts into the fruit, providing nourishment and support.
Seed formation: The zygote undergoes cell division and forms a embryo, a food reserve, and protective layers.
Examples:
The formation of a fruit in apple flowers is triggered by the release of pollen.
The development of a seed in sunflower seeds is associated with the growth of a tiny embryo with a root and two cotyledons.
The fruit of a mango contains numerous small seeds that are dispersed by birds
