Detailed explanation-1: -D. Flowers contain cells that produce gametes. The role of flowers in plant survival is that flowers contain cells that produce gametes. Therefore, option D is correct.

Detailed explanation-2: -The flower’s primary role is to attract pollen matres to the plant to ensure the reproduction and survival of the plant species. Many plants and pollen substances adapt their properties to provide mutually beneficial relationships for each organism.

Detailed explanation-3: -Plants have gametes, which contain half the normal number of chromosomes for that plant species. Male gametes are found inside tiny pollen grains on the anthers of flowers. Female gametes are found in the ovules of a flower. Pollination is the process that brings these male and female gametes together.

Detailed explanation-4: -Flowers in plants carry out the reproductive functions of plants. Male and female gametes are fused to produce the seeds. These seeds bear the fruit which undergoes germination to produce new plant structures. This process of reproduction takes place in the reproductive parts of the flower.

Detailed explanation-5: -The primary purpose of the flower is reproduction. Since the flowers are the reproductive organs of the plant, they mediate the joining of the sperm, contained within pollen, to the ovules-contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.
