- The stigma is a swollen, knob-like structure. It can be either hairy or sticky, or sometimes both to trap pollen grains. In wind-pollinated flowers, like grasses, it may be feathery and branched or elongated. However, for some other flowers, it may be compact and has a sticky surface.

- Sepals. Sepals are modified leaves that typically function as protection for the flower in bud and often as support for the petals when in bloom. They are sterile floral parts and may be either green or leaf-like or composed of petal-like tissue.
- Petals. Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators.
- Stamens. Stamen can be described as the male reproductive part of a flower. In all but a few extant angiosperms, the stamen consists of a long slender stalk, the filament, with a two-lobed anther at the tip.
- Carpel. The pistils of a flower are considered to be composed of one or more carpels. A carpel is the female reproductive part of the flower —composed of ovary, style, and stigma— and usually interpreted as modified leaves that bear structures called ovules, inside which egg cells ultimately form.
The stigma is fixed to the apex of the style, a narrow upward extension of the ovary. The stigma (pl.: stigmas or stigmata) [1] is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower.
Stigma - The stigma is a sticky part at the top of the female parts of a flower. Ovary - Seeds are formed inside the ovary of a flower. Petal - A petal is a part of a flower which is often colourful and attracts insects to pollinate the flower.
