Detailed explanation-1: -Insect-pollinated flowers usually possess sticky and heavy pollens with a rough surface that allow them to stick to insects easily. Flowers also have sweet nectar that attracts insects that go from flower to flower to pollinate the flowers.

Detailed explanation-2: -Pollination is an essential part of plant reproduction. 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-3: -The top of the pistil is called the stigma, which is a sticky surface receptive to pollen.

Detailed explanation-4: -The stigma is the sticky surface at the top of the pistil; it traps and holds the pollen. The style is the tube-like structure that supports the stigma. The style leads down to the ovary which contains the ovules. During the process of pollination, pollen moves from the male parts to the female parts.
