Observe Picture B carefully and answer the following question: What does this part help in?

The part of the plant shown in picture B is a flower. The primary role of the flower is to serve the purpose of reproduction. Since the flower contains reproductive organs, it helps in the process of pollination by transferring the pollen grains from the anther to the stigma of the flower. When the pollen grains fall on the stigma, they move down through the tube called style and reach the ovary. In the ovary, the male sex cells present in pollens join with the female sex cells present in ovules. The joining together of male and female sex cells is called fertilisation. After fertilisation, the ovules grow and become seeds. The ovary of the flower grows and becomes a fruit

Observe Picture B carefully and answer the following question: Why is this part often colourful?

The part of the plant shown in picture B is the flower. It is the most beautiful part of a plant. The flower is often colourful to attract the insects who visit to collect the nectar and achieve the process of pollination. Insects are pollinators. When these visit the flower, the pollen grains from the flower stick to their legs and bodies. When they visit another flower, the pollen grains are dusted on the stigma of that flower. Hence, pollination is achieved.
