AP BIOLOGY

Detailed explanation-1: -Corolla consists of petals which are the coloured part of the flower and attract the insects for pollination.

Detailed explanation-2: -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.

Detailed explanation-3: -Petals are brightly coloured and scented to attract animals and insects for pollination. The calyx and corolla are collectively called the perianth. Different forms of the corolla are found in the flowers. Stamen is also known as the third whorl of the flower and is the male reproductive part.

Detailed explanation-4: -Pollinators visit flowers in search of food, mates, shelter and nest-building materials. The energy that powers pollinator growth, metamorphosis, flight and reproduction comes from sugars in nectar, and the proteins, fats, vitamins and minerals from pollen grains.

Detailed explanation-5: -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.
