Answer 2

→ A flower consists of two parts. One is male part and another is female part.

Male parts consists of long, stalk part called Filament and upper broad portion called Anther. Anther contains pollen grains.

Female parts consists of upper broad portion called Stigma. Middle thin part called Style and the lower portion called Ovary. Ovary conatins ovule.

→ When a pollen grain reach the stigma of the flower then it secretes some liquid substance which is absorbed by pollen grain. After it they form a pollen tube which ultimately reach the ovule of the ovary.

→ Now, the two male gamates (pollen grains) start travelling through this pollen tube and reach the ovule of the ovary, which contains egg and two polar nuclei.

→ When a male gamate fuse with egg then it forms zygote by the process of fertilization and this type of fertilization in plants is known as Syngamy. And when a another male gamate fuse with two polar nuclei, it is known as triple fussion; then it form primary endosperm nucleus. 

Since, the fusion occurs two times. So, this type of fusion is known as as Double Fusion.

→ After is the zygote develops into the embryo and the primary endosperm nucleus into endosperm which provides nourishment to the growing embryo.

After it the ovule develops into seed and ovary into fruit.
