NEET BIOLOGY

Detailed explanation-1: -Petals (collectively called the corolla) are the second whorl of the flower. They are sterile floral parts. The major function of petals is to attract insects for pollination and to protect the reproductive organs, which are at the centre of the flower.

Detailed explanation-2: -Petals attract pollinators to flowers through their colours, scent, and even warmth. Plants which use bats or moths as pollinators typically have evolved to have flowers with white petals and a strong scent.

Detailed explanation-3: -The petals attract pollinators, and the sepal and bract often support the flower. The ovary contains the female reproductive parts, and the stamens (the male reproductive system) store the pollen-though these two parts may have occurred in separate individuals in the ancestral flower.

Detailed explanation-4: -Plants produce nectar to attract pollinators. As the pollinator moves from flower to flower collecting nectar, they are also moving pollen from flower to flower. Certain fruits and seeds will not be produced if their flowers are not pollinated.

Detailed explanation-5: -Petals are brightly pigmented or colored to attract insects for pollination. They also protect the inner floral whorls in bud stage. For example, bees are drawn to plants with open or flat tubular flowers with lots of pollen and nectar.
