- The stigma is part of the female reproductive part of a flower, the pistil. The stigma is on top of the style. The stigma can be either hairy or sticky, or both to trap pollen. When the pollen lands on the stigma, the pollen will grow a pollen tube down the style, and into the ovary of the pistil.

The stigma (pl.: stigmas or stigmata) is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower.
The stamen ( pl.: stamina or stamens) is the pollen-producing reproductive organ of a flower. Collectively, the stamens form the androecium. [1] Morphology and terminology. A stamen typically consists of a stalk called the filament and an anther which contains microsporangia.
stigma. 1. The receptive tip of the carpel, which receives pollen at pollination and on which the pollen grain germinates. The stigma is adapted to catch and trap pollen, either by combing pollen off visiting insects or by various hairs, flaps, or sculpturings.
Gynoecium ( / ɡaɪˈniːsi.əm, dʒɪˈniːʃi.əm /; from Ancient Greek γυνή (gunḗ) 'woman, female', and οἶκος (oîkos) 'house'; pl.: gynoecia) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds.

The stigma is a specially adapted portion of the pistil modified for the reception of pollen. It may be feathery and branched or elongated, as in such wind-pollinated flowers as those of the grasses, or it may be compact and have a sticky surface.
