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 top of the pistil is called the stigma, which is a sticky surface receptive to pollen. The bottom of the pistil contains the ovary and the narrowed region in between is called the style. The male contribution or pollen is produced in the anther, and seeds develop in the ovary.

Detailed explanation-3: -When it comes to pollen discrimination and self-incompatibility reactions, stigma can play a significant influence. As a result, the stigmas of anemophilous flowers are usually rough and sticky. Anemophily, or wind pollination, is a method of pollination in which pollen is spread by wind.
