stigma, usually mounted at the tip of a
style with an
ovary at the base.
Often the entire whorl of carpels is fused into a single pistil.

stigma -- The sticky tip of a pistil. Or, the dense region of pigments found in many photosynthetic protists which is sensitive to light, and thus functions somewhat like a miniature eye.More info?
stipe -- A scientific term for "stalk".

Risk as Stigma - The Redefined Social Bond. When medical professionals encourage or offer genetic testing or other services they usually do so using the language of risk.

stigma The mass of bright red photoreceptor granules found in certain flagellated protozoa (Euglena) that serves as a shield for the photoreceptor. Also the spiracle of certain terrestrial arthropods.

The stigma functions as a receptive surface on which pollen lands and germinates its pollen tube. Corn silk is part stigma, part style. The style serves to move the stigma some distance from the ovary. This distance is species specific.
The Ovary ...

After the pistil is pollinated, the pollen grain germinates in a response to a sugary fluid secreted by the mature stigma called semen.

Normally, the garden pea self-fertilizes but he could prevent self fertilization and cross (breed) two different plants by putting the pollen (sperm) of one on the stigma (female part leading to the ova) of another or he could let them self ...

pollination - the transfer of pollen from the male anther to the female stigma of a flower.

Transfer of pollen (pollination) from the anther of the flower of one plant to the stigma of the flower of a genetically different plant.

Transfer of pollen (pollination) from the anther of a flower to the stigma of the same flower or sometimes to that of a genetically identical flower (as of the same plant or clone).

If it goes to another flower of the same species, that pollen can land on the stigma. From that point, one haploid male nucleus combines with a female nucleus and the other haploid male nucleus combines with a polar nucleus.

pistil. Female part of the flower, usually consisting of ovules, ovary, style, and stigma.

Flower: The part of an angiosperm containing the organs of reproduction (male stamen and female stigma as well as the ovary).

But HIV remains latent in those whose voices are repressed. In sub-Saharan Africa, for example, stigma still surrounds people infected with HIV, and silence impedes progress in controlling the epidemic.
