NEET BIOLOGY

Detailed explanation-1: -Flower colours thus seem to have been introduced as “advertisements” of the presence of nectar, and more specific nectar guides (such as patterns of dots or lines, contrasting colour patches, or special odour patterns) were introduced near the entrance to the flower, pointing the way to the nectar hidden within.

Detailed explanation-2: -Flower shapes Flowers of wind-pollinated plants typically have very small or no petals, making it easier for airborne pollen to come in contact with the stigma. Flowers of animal-pollinated plants usually have larger showy petals of different shapes and sizes to attract pollinators.

Detailed explanation-3: -Pollen from a flower’s anthers (the male part of the plant) rubs or drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma (the female part). The fertilized flower later yields fruit and seeds.

Detailed explanation-4: -Flowers are designed to attract pollinators with their vibrant colors and alluring fragrance, and in return the pollinators feed on the flowers’ nectar and pollen. Pollinators are vital to the endurance of many species of plants and animals-and that doesn’t exclude people.
