BOTANY

Detailed explanation-1: -The top part of the pistil is called the stigma and is sticky so it will trap and hold pollen. In flowering plants, the flower functions in sexual reproduction. The essential flower parts are the male parts called the stamens and the female part called the pistil.

Detailed explanation-2: -The pollen is transferred to the female part of the plant by wind or insects, usually butterflies and bees. The pollen gets stuck to the sticky stigma, pulled down through the style, and into the pistil.

Detailed explanation-3: -Due to the spatial separation between male and female pollen grains from the anther of most flowering plants, including orchids, pollens are transported by wind or animals and deposited onto the receptive surface of the stigma of a different plant.

Detailed explanation-4: -Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma.
