Detailed explanation-2: -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 holds up the stigma. The style leads down to the ovary that contains the ovules. Other parts of the flower that are important are the petals and sepals.

Detailed explanation-3: -Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma.
