State the post-fertilisation changes that lead to fruit formation in plants

After fertilisation in plants, several changes occur that lead to fruit formation. Here are the steps:

1. Fertilisation: The process begins when a pollen grain lands on the stigma of a flower and grows a pollen tube down into the ovary. The sperm cells travel down this tube and fertilise the ovules.

2. Zygote Formation: The fertilised ovule develops into a zygote. This is the first cell of the new plant.

3. Embryo Development: The zygote divides and grows into an embryo inside the ovule. The ovule begins to change into a seed.

4. Endosperm Formation: The primary endosperm cell in the ovule divides to form the endosperm, a tissue that provides nourishment to the developing embryo.

5. Seed Development: The ovule develops into a seed. The outer layer of the ovule hardens to become the seed coat. The embryo inside the seed begins to go dormant.

6. Ovary Development: The ovary of the flower develops into a fruit. It grows larger and begins to ripen. The ripened ovary is what we commonly refer to as the fruit.

7. Fruit Maturation: The fruit continues to mature until it is ready to be dispersed. The seeds inside the fruit are also mature at this point and ready to start new plants.

8. Seed Dispersal: Once the fruit is mature, it is dispersed by various means such as wind, water, or animals. The seeds inside the fruit can then germinate and grow into new plants, continuing the cycle.
