FLOWERS

✴ A typical flower consists of four main whorls namely calyx (sepals), Corolla (Petals), Androecium (Stamens) and Gynoecium (Carpels).

✴ Pollen grains of a flower , transfer to the stigma of the carpel of the same flower (Self Pollination)or to the stigma of carpel of the another flower (Cross-Pollination).

✴ This transfer of pollens is achieved by agent like wind, water or animals.

After Pollination, a pollen tube grows out of pollen grains, through which male germ cell reaches the ovary and fuses with the female germ cell.

✴ Fertilization : The fusion of male and female gamete is called fertilization. It occurs inside the ovary. Zygote is produced in this process.
