How is the gamete of a flower changed into a fruit?

 Germination of pollen on stigma

1)    Pollen grains are produced by the male reproductive part, stamen. Ovules are found in the ovary, and each ovule contains an egg cell.

2)     From the stamen to the stigma, pollen must be transported. Self-pollination is the term used to describe the transfer of pollen when it takes place within the same flower.

3)    On the other hand, cross-pollination refers to the transfer of pollen from one flower to another.

4)    The pollen must then travel to the female germ cells in the ovary after it has landed on an appropriate stigma. The male germ cell formed by the pollen grain fuses with the female gamete present in the ovule in order to achieve this, as shown in Figure, which is accomplished by a tube growing out of the pollen grain and travelling through the style to the ovary.

5)    The zygote is produced by the fusion of the germ cells. This process is known as fertilisation.

6)    After fertilisation, the zygote splits multiple times inside the ovule to create an embryo.

7)    The ovule gradually changes from an ovule to seed by developing a thick covering.

8)    The ovary expands rapidly and matures to become a fruit.

9)    Petals, sepals, stamens, styles, and stigma may shrink and fall off in the meantime.
